Sacred Oils and Scents: History, Ritual Traditions and Safe Use
Sacred oils have perfumed temples, anointed kings and carried prayers for at least three thousand years. This article traces where the classic sacred scents come from and how each tradition used them. It also covers what modern research shows about aromatherapy and how to use these oils safely and sustainably.
This article is for information only and is not medical advice. Talk to a doctor before using any remedy, especially for a diagnosed condition, during pregnancy or for a child.
Call Poison Help at 1-800-222-1222 (US) right away. For pets, call ASPCA Animal Poison Control at (888) 426-4435. Call emergency services for drowsiness, choking, coughing fits, breathing trouble or a seizure. Even a teaspoon of some oils can be dangerous for a child.
What makes an oil “sacred”?
No plant is sacred by chemistry. A scent becomes sacred through use. Resins, woods and flowers earned that status by being burned on altars, rubbed into skin at ceremonies or offered to gods. The same frankincense sold today as an essential oil once crossed deserts by camel.
It also helps to know that “oil” covers several very different products. Ancient anointing oils were not the concentrated essential oils sold now. They were usually fragrant materials steeped in olive or sesame oil, far milder on the skin.
| Product | How it is made | Strength | Example |
|---|---|---|---|
| Essential oil | Steam distillation, or cold pressing for citrus peel | Highly concentrated; must be diluted | Frankincense, lavender |
| Absolute | Solvent extraction of delicate flowers | Very concentrated | Rose absolute, jasmine |
| Infused oil | Plant material steeped in a fatty oil | Mild | Biblical-style anointing oils |
| Attar | Flowers distilled into sandalwood oil | Concentrated, oil-based perfume | Indian rose attar |
| Fragrance oil | Blended, often synthetic, perfume compounds | Varies | Most “lilac”, “peach”, “cherry” or “amber” oils |
That last row matters. Lilac, peony, peach and cherry blossom do not yield commercial essential oils, so products with those names are fragrance blends. “Amber” oil is usually a perfumer’s accord of resins and vanilla rather than fossil amber. They can smell lovely, but they are not traditional sacred oils.
Sacred oils and incense through history
Encyclopaedia Britannica traces incense through almost every major religious tradition. The pattern is remarkably consistent. Fragrant smoke rose toward the divine, purified a space or honored the dead.
Incense trees were imported from the Arabian and Somali coasts. Incense filled daily temple rites for the sun god Amon-Re. In funeral rites, the smoke was believed to carry the soul of the dead to heaven.
Exodus 30 describes a holy anointing oil of myrrh, cinnamon, calamus and cassia in olive oil. Its holy incense blended frankincense with stacte, onycha and galbanum in equal parts.
From the 8th century BC, Greeks burned woods and resins as offerings and for protection from demons. Rome later used imported incense in sacrifices and the imperial cult.
The church adopted incense in the Eucharist in the 4th century AD, as a symbol of rising prayer. Catholic and Eastern Orthodox worship still use it. Chrism, a scented oil, anoints at baptism and confirmation.
Hindus offer incense in temple and household worship, and Buddhists burn it in daily rites. Sandalwood paste marks the forehead in Hindu practice. Ayurveda uses fragrant oils in massage.
In China, incense honored ancestors and household gods at festivals. Japan folded it into Shintō ritual and developed kōdō, a refined art of “listening” to incense.
One shift is worth knowing. Britannica notes that from the 17th and 18th centuries, perfume chemistry increasingly replaced natural ingredients. Many “sacred” scents sold today owe more to that history than to the temple.

The classic sacred oils: a profile of each scent
Each profile below separates three things: what the plant is, how traditions used it, and what you should know before using it. Traditional uses describe beliefs and customs, not proven effects.
Frankincense
Source: Resin of Boswellia trees, such as Boswellia sacra and Boswellia papyrifera, in the Burseraceae family. The oil is steam-distilled from the hardened resin. Tradition: the central incense of Egyptian, Israelite and Christian worship, and one of the gifts of the Magi. Know before you use it: wild frankincense trees are in serious decline, covered in the sustainability section below. More detail is in our frankincense oil profile.
Myrrh
Source: Resin of Commiphora myrrha, a thorny shrub from the same family as frankincense. Tradition: the largest ingredient in the anointing oil of Exodus, and used in ancient Egyptian funeral practice. Know before you use it: ask a doctor or qualified aromatherapist before using myrrh, like any concentrated oil, during pregnancy.
Sandalwood
Source: Heartwood of Santalum album, Indian sandalwood. Only the heartwood is fragrant, and trees are usually harvested after about 20 years. Tradition: sandalwood paste in Hindu worship, and the base oil for Indian attars. Know before you use it: the IUCN Red List classes Indian sandalwood as Vulnerable. Plantation-grown Indian or Australian sandalwood is the more responsible choice.
Rose
Source: Usually Rosa damascena, the Damask rose. Rose otto is steam-distilled; rose absolute is solvent-extracted. Tradition: a symbol of love and the divine in Persian, Indian and Christian imagery, and a classic attar. Know before you use it: a little oil takes an enormous quantity of petals. Cheap “rose oil” is often diluted or synthetic. See our rose oil profile.
Palo santo
Source: Wood of Bursera graveolens, another frankincense relative, native from Mexico to Peru. Tradition: “holy wood” burned in Andean and South American ritual to clear a space. Know before you use it: the IUCN rated the species Least Concern in 2019. Peru has allowed only naturally fallen or dead wood to be collected since 2006. Ask sellers how their wood was sourced. Read more in our palo santo oil profile.
Cedarwood
Source: “Cedarwood oil” can come from true cedars, such as Atlas cedar (Cedrus atlantica), or from junipers sold as Virginian cedarwood. Check the botanical name on the label. Tradition: cedar timber was prized for temples and sacred buildings across the ancient Near East. Know before you use it: different species smell and behave differently, so they are not interchangeable.
Vetiver
Source: Roots of Chrysopogon zizanioides, a tall grass. The oil is thick, smoky and earthy. Tradition: in India, called khus, its roots were woven into screens that cooled and scented homes in summer. Know before you use it: its heavy scent goes a long way, so a little is plenty.
Lavender
Source: Flowers of Lavandula angustifolia, in the mint family (Lamiaceae). Tradition: a European cleansing and bathing herb, later the face of modern aromatherapy. Know before you use it: lavender is one of the few oils with some clinical research, covered below. It also carries a caution for young boys, covered in the safety section. More in our lavender oil profile.
Chakras and oils: a modern pairing, not an ancient one
Many sites match each chakra to a set of oils. It is worth knowing where that idea comes from. The chakras come from Hindu and Buddhist tantric texts. Pairing each chakra with specific essential oils is a modern Western addition from the late 20th century, not part of those texts.
The table below shows commonly cited pairings as modern belief. It describes how some practitioners work, not an effect on the body.
| Chakra (Sanskrit) | Meaning of the name | Oils often paired in modern practice |
|---|---|---|
| Root (Mūlādhāra) | Root support | Vetiver, patchouli, cedarwood |
| Sacral (Svādhiṣṭhāna) | One’s own abode | Sweet orange, ylang-ylang |
| Solar plexus (Maṇipūra) | City of jewels | Ginger, lemongrass |
| Heart (Anāhata) | Unstruck sound | Rose, geranium |
| Throat (Viśuddha) | Purification | Eucalyptus, peppermint |
| Third eye (Ājñā) | Command | Sandalwood, frankincense |
| Crown (Sahasrāra) | Thousand-petaled | Frankincense, sandalwood |
Pairings vary between teachers and have no basis in research. Eucalyptus and peppermint are unsuitable near young children’s faces.
What research says about sacred oils and aromatherapy
Scent clearly affects how people feel in the moment. The harder question is whether aromatherapy changes health outcomes. Here the evidence is thin and mostly low quality.
| Source | What it found |
|---|---|
| Cochrane Australia for the NHMRC, 2024 | 323 trials reviewed. No confident conclusions possible for any condition; all evidence low or very low certainty. Possible small benefits for sleep, some pain and pregnancy nausea. |
| NCI cancer information (PDQ), 2023 | Mixed results. Inhaled lavender eased pain during port needle insertion. A trial of 313 radiation patients found no anxiety difference between oils. |
| Cochrane review, dementia, 2020 | 13 studies, 708 people. No convincing evidence of benefit. |
| NCCIH | Too little rigorous research to say whether aromatherapy helps insomnia. Lemon scent lifted mood in one study, but had no effect on stress or immune markers. |
The fair summary is that scent may be a pleasant comfort, especially in hospital settings, but it is not a treatment. The NCI notes that aromatherapy products do not need FDA approval. No oil has been approved to treat any disease. If you have a health condition, see a doctor; an oil can sit alongside care but never replace it.
Essential oil safety: dilution, skin, children and pets
Concentration is the reason essential oils need care. A single drop can hold the aromatic compounds of a large handful of plant material. The Tisserand Institute’s first rule is simple: do not apply undiluted essential oils to your skin.
How to dilute
A Mayo Clinic patient handout states that 1% to 5% dilutions in a carrier oil do not typically pose a safety concern for adults. The risk of a skin reaction rises with strength. Its example: 1% is about 1 drop of essential oil in 1 teaspoon (5 ml) of carrier oil.
| Dilution | In 5 ml (1 tsp) | In 10 ml | In 30 ml (1 fl oz) |
|---|---|---|---|
| 0.5% | Less than 1 drop | 1 drop | 3 drops |
| 1% | 1 drop | 2 drops | 6 drops |
| 2% | 2 drops | 4 drops | 12 drops |
| 3% | 3 drops | 6 drops | 18 drops |
Based on the Mayo Clinic example of 1 drop per 5 ml at 1%. Drop sizes vary between bottles, so treat these as approximate. Use lower strengths on the face.
Oils with their own limits
- Skin allergy risk: the Tisserand Institute caps clove bud at 0.5%. It names lemongrass, clove and cinnamon bark as more likely to cause skin reactions.
- Sun sensitivity (phototoxicity): some cold-pressed citrus oils can cause burns or dark patches on sun-exposed skin. Tisserand limits lemon to 2% and grapefruit to 4% on skin that will see sun. Expressed bergamot is a well-known phototoxic oil; “FCF” or bergapten-free versions avoid this.
- Old oils: oxidized oils irritate more. Keep bottles tightly closed, cool and dark.
Never swallow essential oils
The Tisserand Institute advises against oral use unless a qualified practitioner recommends it. Vanderbilt University Medical Center’s poison center lists oils behind serious poisonings. As little as one teaspoon of camphorated oil has killed children. Wintergreen is almost pure methyl salicylate, a close chemical relative of aspirin. Eucalyptus deaths have followed as little as 4 ml.
Children, pregnancy and hormones
- Store every oil out of children’s reach, with child-resistant caps.
- The Mayo Clinic handout says birch, wintergreen and peppermint should not be used with young children. Talk to a child’s doctor before using any oil on their skin.
- The NCI notes that lavender and tea tree oils have shown estrogen-like effects. A 2007 New England Journal of Medicine report linked repeated skin use to breast growth in three young boys. It resolved after the products were stopped.
- If you are pregnant, breastfeeding, have epilepsy or asthma, or take prescription medicine, ask a doctor before using oils.
Pets
ASPCA guidance warns that cats, rabbits, guinea pigs and hamsters are especially sensitive. They groom oil off their fur and swallow it. Birds are at risk from diffused oils because of their delicate lungs. Tea tree and pennyroyal oils are linked to seizures and, rarely, liver injury in pets.
- Never apply concentrated oils to a pet or give them by mouth.
- No diffusers in a home with birds.
- Keep diffusers out of reach, and let pets leave the room if the scent is strong.
- Signs of trouble include drooling, vomiting, wobbliness, weakness, breathing problems or seizures. Call (888) 426-4435.
Diffusers, incense and flames
The Tisserand Institute suggests diffusing in cycles of 30 to 60 minutes on, then 30 to 60 minutes off, with fresh air circulating. Essential oils are flammable, so keep them away from open flames and avoid candle-heated burners. Burn incense and palo santo in a ventilated room, away from anyone with asthma.
Sustainability: protecting the trees behind sacred oils
The sacred scents most in demand come from slow-growing wild trees. Ethical buying is now part of honoring these traditions.
A 2019 Nature Sustainability study of 23 Boswellia papyrifera sites found almost no young trees in 18. Grazing, fire, insects and overtapping drive the decline. Researchers projected production could halve within two decades.
The IUCN lists Santalum album as Vulnerable after over-harvesting, fire and disease. Choose certified plantation sources.
Bursera graveolens is rated Least Concern. Responsible supply uses only fallen, naturally dead wood, as Peruvian rules require.
- Is the Latin botanical name on the label?
- Does the seller state the country of origin and harvest method?
- For frankincense and sandalwood, is the supply traceable or plantation-grown?
- Is the price realistic? Very cheap rose or sandalwood is often diluted or synthetic.
- Is it a dark glass bottle with a dropper cap and a batch number?
Using scent in ritual, safely
Most traditions used scent in gentle ways: a whiff of smoke, a touch of oil. Copying that restraint is also the safest approach today.
Smell first
Open the bottle and inhale gently, or place a drop on a tissue.
Diffuse in cycles
30 to 60 minutes on, then off. Keep pets and birds in mind.
Anoint diluted
Blend into a carrier oil, around 1% for wrists or neck.
Patch test
Try a diluted blend on a small patch of skin before wider use.
A simple anointing blend in the spirit of the old traditions might use frankincense or sandalwood in jojoba oil. At about 1%, that means 1 drop per teaspoon of carrier. It is a ritual and a pleasure, not a treatment. Explore individual scents in our oils and scents collection.
Common mistakes with sacred oils
- Dabbing neat oil on the temples or soles. Undiluted oil can irritate or sensitize skin over time. Dilute first.
- Adding drops straight to bathwater. Oil floats and hits skin undiluted. Tisserand advises mixing it into a suitable base first, and says milk and Epsom salts do not work.
- Mixing oils into a water spray without shaking. Oils do not dissolve in water, so a room spray delivers uneven, concentrated droplets.
- Using citrus oils before sun exposure. Some cause burns or dark patches.
- Diffusing all day around cats or birds. Use short cycles in rooms pets can leave.
- Trusting “therapeutic grade” labels. It is a marketing term, not a regulated standard.
- Using an oil instead of seeing a doctor. No essential oil is approved to treat any disease.
One small ritual to start with
Choose one sacred scent and get to know it slowly. Before your next quiet moment, place a single drop of frankincense or sandalwood on a tissue nearby. Breathe it in for a few minutes, and keep the bottle capped and out of reach afterward. That is how incense was always meant to work: a little scent, a pause and a moment of attention.
