18 Essential Oil Candle Recipes With Clean, Calming Scent Blends

You want the house to smell like something without a chemistry degree or a trip to a candle shop that charges thirty dollars for ‘quiet luxury.’ Soy wax, a handful of essential oils and an afternoon get you there, and every blend below is built the same way: wax by weight, wick by size, scent by the drop, not by vibes.

Keep a kitchen scale, a pouring pitcher, a candle thermometer and pre tabbed wicks with stickers on hand, plus two clothespins or a wick centering tool to hold the wick straight while the wax sets. One candle takes about thirty minutes of actual work from melting to pouring. The scent takes longer: soy wax needs real cure time before it throws properly, which is the step everyone skips and then blames the recipe for.

One honest note before you start: essential oils are not fragrance oils. Many burn off at wax temperature, citrus is famously weak once it is locked in soy, and a blend that smells strong in the bottle can go quiet in the jar. Where that matters, each entry says so plainly rather than promising a throw the oil cannot give. If you want shapes beyond a jar once you are hooked, 39 Candle Making Ideas That Look Nothing Like a Jar Candle is the next stop, and a tray of luxurious bath salts makes a nice pairing gift.

Lavender Cedar Calm

This is the one for the evening you cannot quite shake off your shoulders yet. Lavender does the talking, bergamot lifts it so it does not smell like a pillow spray, and cedarwood sits underneath so the whole thing reads grown up rather than sleepy-time tea. Burn it on the nightstand or by the bath, and if you would rather skip the jar entirely, the same blend works as a wax melt in a warmer.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 90 drops bergamot essential oil
• 150 drops lavender essential oil
• 60 drops cedarwood essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the bergamot, lavender and cedarwood.
3. Stir gently for a full 60 seconds so the oils spread through the wax, not just the top inch.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Eucalyptus Spa Steam

Burn this one after a workout, or on the day the shower is the only five minutes of peace you get. Peppermint hits first and sharp, eucalyptus carries the bulk of the spa feeling, and tea tree sits underneath to keep it medicinal rather than sweet. It reads less like a candle and more like the inside of a good steam room.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 90 drops peppermint essential oil
• 120 drops eucalyptus essential oil
• 60 drops tea tree essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the peppermint, eucalyptus and tea tree.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Citrus Ginger Wake-Up

Here is the fair warning first: citrus is a famously weak performer once it is trapped in soy wax, so do not expect this to hit you across the room the way a bottle of sweet orange oil does on the counter. What it does give is a bright, gingery lift, good for a kitchen candle lit while coffee brews, and the ginger root underneath gives the orange something to hold onto.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 150 drops sweet orange essential oil
• 140 drops lemongrass essential oil
• 90 drops ginger essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 125F, cooler than usual, to protect the fragile citrus top note.
3. Add the sweet orange, lemongrass and ginger, then stir gently for a full 60 seconds.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Rosemary Garden Mint

Think of this as the smell of a herb bed after rain rather than anything sweet. Spearmint keeps rosemary from going medicinal, and clary sage underneath gives it a soft, almost tea-like finish. It suits a kitchen windowsill or a desk where you need to think clearly, and it is cheap to make since all three oils sit at the lower end of the price shelf.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 90 drops spearmint essential oil
• 150 drops rosemary essential oil
• 60 drops clary sage essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the spearmint, rosemary and clary sage.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Cedar Vetiver Study

For the room where she actually works, not the one staged for guests. Black pepper gives it a small, warm bite up front, cedarwood fills the middle, and vetiver underneath reads smoky and a little damp, like a library after the radiator kicks on. It suits a small tin on a desk rather than a jar that dominates the room, and it burns slowly enough to last a whole season of late nights.

Active time: 25 minutes. Cure time: 14 days. Yield: one 6 oz tin.

What You Need

• 4.8 oz soy wax flakes for a 6 oz tin
• one 6 oz metal candle tin, about 2.75 inches across
• one CD-8 wick
• 50 drops black pepper essential oil
• 100 drops cedarwood essential oil
• 50 drops vetiver essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the black pepper, cedarwood and vetiver.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the tin with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Sandalwood Vanilla Hush

This is the blend for the woman who says she does not like ‘sweet’ candles and then burns this one for a week straight. Cardamom opens it with a little spice, sandalwood carries the warmth, and vanilla oleoresin underneath keeps it from turning into dessert. Warm the vanilla jar in your hands first if it has thickened, since it pours more easily once loosened.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 55 drops cardamom essential oil
• 135 drops sandalwood essential oil
• 80 drops vanilla oleoresin
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the cardamom, sandalwood and vanilla oleoresin.
3. Stir gently for a full 60 seconds, a little longer if the vanilla is slow to blend in.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Patchouli Clove Night

You either already love patchouli or you think you hate it because of one bad incense stick in college; this blend is for the first group. Clove bud adds a warm, almost mulled edge in a very small dose, patchouli does the heavy lifting, and amyris underneath smooths the whole thing so it reads rich rather than dusty. Give it the full three weeks of cure: resinous oils like these need the extra time to settle into the wax.

Active time: 30 minutes. Cure time: 21 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 35 drops clove bud essential oil
• 140 drops patchouli essential oil
• 55 drops amyris essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the clove bud, patchouli and amyris.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for a full 21 days out of direct sunlight before the first burn.

Frankincense Myrrh Quiet

Burn this for the evening you want the room to feel like a pause rather than a party. Sweet orange keeps the resins from going heavy, frankincense is the real centre of the blend, and myrrh underneath gives it that slightly dusty, church-on-a-Sunday warmth. It suits a reading chair more than a dinner table, and like the patchouli blend above it rewards patience: let it cure the full three weeks.

Active time: 30 minutes. Cure time: 21 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 70 drops sweet orange essential oil
• 150 drops frankincense essential oil
• 50 drops myrrh essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the sweet orange, frankincense and myrrh.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for a full 21 days out of direct sunlight before the first burn.

Rose Geranium Bloom

Not a soapy rose, something earthier. Bergamot opens it, rose geranium is the whole point, and a small amount of sandalwood keeps it from reading like a bar of guest soap. This one is sized small on purpose: a 4 oz tin makes a proper gift for a friend who just redid her bathroom, and it costs barely anything to make two or three at once.

Active time: 20 minutes. Cure time: 14 days. Yield: one 4 oz tin.

What You Need

• 3.2 oz soy wax flakes for a 4 oz tin
• one 4 oz metal candle tin, about 2.25 inches across
• one CD-6 wick
• 45 drops bergamot essential oil
• 75 drops rose geranium essential oil
• 30 drops sandalwood essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the bergamot, rose geranium and sandalwood.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the tin with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Fir Balsam Forest

Skip this if you already own three pine candles from the grocery store; this is not that. Black spruce opens bright and almost citrusy, fir needle is the sweet, sappy centre, and cedarwood underneath keeps the whole thing dry instead of sickly sweet. It is the one to burn with a wool throw over your knees, and it does not need a special occasion.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 70 drops black spruce essential oil
• 150 drops fir needle essential oil
• 50 drops cedarwood essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the black spruce, fir needle and cedarwood.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Lemon Basil Kitchen

This smells like a windowsill herb pot more than a cleaning product, which is the whole point. Lemon fades fastest of anything on this list, so this blend pushes the load to the top of the safe range to compensate, basil fills the gap behind it, and petitgrain underneath keeps it green rather than purely citrus. Burn it while you cook, not before guests arrive expecting it to fill the room.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 160 drops lemon essential oil
• 120 drops basil essential oil
• 70 drops petitgrain essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 125F, cooler than usual, to protect the lemon top note.
3. Add the lemon, basil and petitgrain, then stir gently for a full 60 seconds.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Grapefruit Mint Spritz

This is the one for a bathroom that gets no natural light and needs to feel awake anyway. Pink grapefruit carries most of the blend, spearmint keeps it from smelling like a cocktail, and a small amount of vetiver at the base stops it from fading into nothing after twenty minutes. Citrus candles like this one do best lit in short bursts rather than left burning all evening.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 170 drops pink grapefruit essential oil
• 130 drops spearmint essential oil
• 50 drops vetiver essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 125F, cooler than usual, to protect the grapefruit top note.
3. Add the grapefruit, spearmint and vetiver, then stir gently for a full 60 seconds.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Chamomile Lavender Nightcap

For the nights that need less stimulation, not more. Roman chamomile opens soft and a little apple-like, lavender sits in the middle doing most of the calming work, and vanilla oleoresin underneath keeps it warm rather than medicinal. The fragrance load here sits deliberately low: this is meant to be a whisper in the room, not a wall of scent at 10pm.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 70 drops roman chamomile essential oil
• 110 drops lavender essential oil
• 50 drops vanilla oleoresin
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the chamomile, lavender and vanilla oleoresin.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Clary Sage Citrus Spa

This is a spa candle without the eucalyptus everyone else reaches for. Lime keeps it bright up top, clary sage gives it that herbal, almost wine-like heart note, and ylang ylang underneath adds a floral weight that stops it feeling thin. It suits a long bath more than a quick shower, since it builds slowly rather than announcing itself the moment it is lit.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 130 drops lime essential oil
• 110 drops clary sage essential oil
• 60 drops ylang ylang essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the lime, clary sage and ylang ylang.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Juniper Pepper Lodge

If your living room is big enough to swallow a single 8 oz jar whole, this is the one to make instead: a 16 oz double wick candle built to actually fill the space. Juniper berry gives it a green, slightly gin-like snap, black pepper adds warmth in the middle, and vetiver underneath grounds the whole thing so it reads lodge rather than liquor cabinet. Let the whole melt pool reach both wicks evenly on the first burn.

Active time: 40 minutes. Cure time: 21 days. Yield: one 16 oz candle.

What You Need

• 12.8 oz soy wax flakes for a 16 oz jar
• one 16 oz glass jar, about 4 inches across
• two CD-12 wicks, set side by side
• 200 drops juniper berry essential oil
• 180 drops black pepper essential oil
• 160 drops vetiver essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 135F, then add the juniper berry, black pepper and vetiver.
3. Stir gently for a full 90 seconds, longer than usual, so the larger batch blends evenly.
4. Pour into the jar with both wicks centered and taped, spaced evenly apart on a flat surface.
5. Let it set at room temperature for at least 6 hours, then trim both wicks to a quarter inch.
6. Cure for a full 21 days out of direct sunlight before the first burn.

Cinnamon Clove Spice Market

Both cinnamon leaf and clove bud are strong enough to sputter a flame or scorch at too high a dose, which is why this blend sits at the low end of the fragrance range on purpose. Clove bud opens it, cinnamon leaf carries most of the warmth, and sweet orange underneath keeps it from tipping into mulled wine territory. It is a small jar made for a short, cold afternoon, not an all day burn.

Active time: 30 minutes. Cure time: 21 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 35 drops clove bud essential oil
• 130 drops cinnamon leaf essential oil
• 65 drops sweet orange essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the clove bud, cinnamon leaf and sweet orange.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for a full 21 days out of direct sunlight before the first burn.

Neroli Petitgrain Linen

This is the closest this list gets to a clean laundry candle, and it earns it honestly rather than through a fragrance house’s idea of ‘fresh.’ Petitgrain carries most of the weight since it holds up better in wax than its orange blossom cousin, true neroli adds a soft floral lift, and sandalwood underneath keeps it from smelling like detergent. If neroli feels like a splurge, lean harder on petitgrain and skip it; the candle still reads clean.

Active time: 30 minutes. Cure time: 14 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 160 drops petitgrain essential oil
• 120 drops neroli essential oil
• 70 drops sandalwood essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 125F, cooler than usual, to protect the delicate top notes.
3. Add the petitgrain, neroli and sandalwood, then stir gently for a full 60 seconds.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for 14 days out of direct sunlight before the first burn.

Palo Santo Amber Dusk

For the last candle of the night, after the dishes are done and nobody is coming over. Black pepper gives it a faint warmth up top, palo santo is the whole reason to make this one, sweet and a little smoky without any actual smoke, and vetiver underneath keeps it from floating away too fast. Give it the full three week cure: palo santo in particular needs the time to stop smelling raw.

Active time: 30 minutes. Cure time: 21 days. Yield: one 8 oz candle.

What You Need

• 6.4 oz soy wax flakes for an 8 oz jar
• one 8 oz glass jar, about 3 inches across
• one CD-10 wick
• 55 drops black pepper essential oil
• 150 drops palo santo essential oil
• 65 drops vetiver essential oil
• a wick sticker and a candle thermometer

How to Make It

1. Melt the soy wax flakes in a pouring pitcher set over simmering water until it reads 185F.
2. Remove from heat and let it cool to 130F, then add the black pepper, palo santo and vetiver.
3. Stir gently for a full 60 seconds so the oils spread through the wax evenly.
4. Pour into the jar with the wick centered and taped, on a flat, draft free surface.
5. Let it set at room temperature for at least 4 hours, then trim the wick to a quarter inch.
6. Cure for a full 21 days out of direct sunlight before the first burn.

Frequently Asked Questions

How many drops of essential oil do you put in a candle?

It depends on the wax weight, not a fixed number of drops. For soy candles, the typical recommendation is to add a fragrance load of 6% to 10%, which for a 6.4 oz pour works out to roughly 230 to 380 drops total, split across your chosen oils rather than dumped in as one scent.

Can I use essential oils instead of fragrance oil in candles?

You can, and every recipe above does exactly that, but temper your expectations on strength. You’ll need to use quite a bit of oil, as the scent dulls significantly when poured into wax, and at least 45 drops per 8oz candle for a subtle scent is a realistic starting point; fragrance oils are built for wax in a way essential oils simply are not.

Why doesn’t my essential oil candle smell like anything when it burns?

Most often it is the fragrance load sitting too low, the wax never reaching full melt temperature before the oils go in, or not enough cure time. Citrus oils are the usual culprits too, since they fade fastest of any note once locked in soy and need the higher end of the load range just to register.

What is the best wax for essential oil candles?

Soy wax is the standard choice for this kind of blend. Beeswax doesn’t hold on to the scent of the oils the way you’d like, and soy wax works better for essential oil candles, since it does not compete with its own natural smell the way beeswax does.

How long do homemade candles need to cure before burning?

Give a standard soy candle at least 14 days before the first burn, and closer to 21 days for anything built around resins, woods or spice oils like patchouli, frankincense or clove. Cure time is when the fragrance finishes binding to the wax, and skipping it is the single most common reason a homemade candle smells like nothing.

Are essential oil candles safe to burn around cats?

Not always, and it depends entirely on which oils are in the blend. Citrus oils, tea tree, eucalyptus, pine, clove, cinnamon and ylang ylang are all common cautions for cats, so check the safety line on any blend before lighting it in a shared room, and skip the stronger ones entirely in a multi-pet household.
