Quick answer: ho wood essential oil is steam distilled from the wood, leaves or twigs of a linalool-rich chemotype of Cinnamomum camphora, the camphor laurel tree. It smells sweet, woody and softly floral, and it is high in linalool, the same compound that gives lavender and rosewood much of their scent. Perfumers and soap makers often use it as a more sustainable stand-in for rosewood oil. White camphor oil, which is dominated by camphor, is a different and much more hazardous product. Dilute ho wood to about 1 to 2 percent for adult skin, never swallow essential oils, and take care around children and pets.
If you have looked for rosewood essential oil and found it expensive or ethically complicated, you have probably run into ho wood. The oil smells similar, it blends in the same way, and it comes from a tree that is far easier to grow and harvest. Because ho wood comes from the camphor laurel tree, a species known for camphor, the name can be confusing. What separates the two is the chemotype, the particular chemical profile of the plant. This profile is part of our essential oils guide. It explains what ho wood oil is, how it differs from camphor and rosewood, and how to use it safely.

What Ho Wood Essential Oil Is
Ho wood oil is made from Cinnamomum camphora, the camphor laurel (also called camphor tree), an evergreen tree native to parts of East Asia, including China, Taiwan and Japan. Different individual trees and populations make very different essential oils, so botanists and distillers talk about chemotypes. A single species can have a camphor chemotype, a cineole chemotype, a safrole chemotype and a linalool chemotype.
The oil sold as ho wood, ho leaf or ho sho comes from the linalool chemotype. A distiller steams the wood chips, or the leaves and twigs, and collects a clear, colorless to pale yellow oil with a smooth, sweet, woody and lightly floral scent. Many people find it softer than lavender and warmer than petitgrain.
The name “ho” is the Chinese or Japanese word for the tree’s linalool-rich form, and the oils are named differently in different markets. Ho wood generally refers to oil from wood, ho leaf to oil from leaves, and both can be used in similar ways. Their chemistry is close, but not identical, and labels do not always make the distinction clear.
What Is in Ho Wood Oil
The main compound in ho wood is linalool, often making up around 80 to 95 percent of the oil, depending on the batch. The rest is made up of small amounts of terpenes such as alpha-terpineol, cineole, limonene and others. Because linalool dominates, the scent is consistent and simple.
Linalool is a fragrant alcohol found in lavender, coriander seed, rosewood, clary sage and many flowers. It is generally considered to have low toxicity, but it can cause allergic reactions in some people when it oxidizes, which is why fresh oil and small bottles are sensible. The European fragrance labeling rules list linalool as an allergen that must be declared on cosmetics above certain concentrations, and many cosmetic brands now list it in their ingredients.
Ho Wood Is Not Camphor Oil
This is the most important point for safety. The same tree gives several oils with very different safety profiles.
| Oil | Chemotype | Main compound | Safety notes |
|---|---|---|---|
| Ho wood / ho leaf | Linalool | Linalool | Gentle; follow normal dilution |
| White camphor | Camphor | Camphor | Toxic in small amounts and especially dangerous for children; not for home use |
| Brown and yellow camphor | Safrole-rich fractions | Safrole | Hazardous; not for aromatherapy |
| Cineole camphor (sometimes sold as “camphor” or “ravintsara”) | Cineole | 1,8-cineole | Avoid around babies and young children |
Our profile of camphor essential oil explains why camphor-rich oils need special caution. If a bottle says only “camphor” without a chemotype, do not use it in the same way as ho wood. Always check the botanical name and the chemotype (“ct. linalool”) on the label.
Ho Wood vs Rosewood
Ho wood is often sold as a substitute for rosewood oil. The two share a large amount of linalool and a similar scent, but they come from very different plants.
| Feature | Ho wood | Rosewood |
|---|---|---|
| Plant | Cinnamomum camphora (linalool chemotype) | Aniba rosaeodora |
| Origin | China, Taiwan, Japan and other regions | Amazon rainforest |
| Scent | Sweet, woody, slightly camphor-like at first | Sweet, woody, soft floral |
| Main compound | Linalool | Linalool |
| Sustainability | Fast-growing tree; leaf and twig distillation is renewable | Slow-growing tree listed as endangered and on CITES Appendix II |
| Price | Lower | Moderate to high |
Ho wood has a slightly sharper, more camphor-tinged opening than rosewood, which fades to a similar soft base. It is not identical, but many perfumers and soap makers consider it a good alternative. If you care about forest conservation, ho wood is generally an easier choice to defend, although you should still check that the oil comes from a reputable source.
What People Use Ho Wood Oil For
Research on ho wood specifically is limited. Most of what is said about it comes from the chemistry of linalool and from traditional use of related oils. The NCCIH notes that research on aromatherapy overall is limited and mixed. Common uses include:
- Scent and mood: many people find the soft, woody-floral scent calming. It is often used in evening diffuser blends.
- Sleep routines: like lavender, it is used in bedtime blends. The routine is likely to matter as much as the oil.
- Skin-care products: because it is gentle, it is used in facial oils, lotions and balms at low dilution.
- Natural perfume: it works as a heart note in floral, citrus and woody blends.
- Cleaning and linen sprays: its clean scent suits homemade sprays.
Claims that ho wood oil treats insomnia, anxiety, acne, infections or any other condition are not proven. In the United States, products marketed to treat disease can be regulated by the FDA as drugs.
How to Use Ho Wood Essential Oil
In a Diffuser
Use three to five drops in about 100 milliliters of water in an ultrasonic diffuser, and run it for 30 to 60 minutes at a time in a ventilated room. Some blends to try:
- Quiet evening: 3 drops ho wood, 2 drops lavender, 1 drop cedarwood.
- Soft floral: 3 drops ho wood, 2 drops geranium, 1 drop sweet orange.
- Fresh woodland: 3 drops ho wood, 2 drops pine, 1 drop lemon.
In Skin Care
Ho wood is commonly added to facial and body products. For facial use, keep dilution to 0.5 to 1 percent, which is 3 to 6 drops per ounce (30 milliliters) of carrier oil. For body oils and lotions, 1 to 2 percent is a usual range, which is 6 to 12 drops per ounce. Stop if you notice redness or itching.
In a Roller Bottle
For a 10 milliliter roller, 2 to 4 drops of oil in carrier oil gives about 1 to 2 percent. Apply to the wrists or the back of the neck, and avoid eyes, mucous membranes and broken skin.
In a Bath
Mix up to 6 drops with a tablespoon of carrier oil or unscented body wash before adding to the water. Essential oils float on water, and undiluted drops can irritate skin.
Safe Dilution at a Glance
| Use | Typical dilution | Drops per ounce (30 ml) of carrier |
|---|---|---|
| Face (leave-on) | 0.5 to 1 percent | 3 to 6 |
| Body oil or lotion | 1 to 2 percent | 6 to 12 |
| Roller bottle | 1 to 2 percent | 6 to 12 |
| Diffuser | 3 to 5 drops per 100 ml water | Not applicable |

Safety and Side Effects
- Never swallow essential oils. If someone swallows ho wood or any other essential oil, call Poison Control at 1-800-222-1222 in the United States.
- Check the label. Make sure the bottle says ho wood or ho leaf, Cinnamomum camphora ct. linalool, and not just camphor.
- Patch test. Apply a diluted drop to the inside of the forearm, cover it and wait 24 hours. Stop if you see redness, itching or swelling.
- Use fresh oil. Oxidized linalool is more likely to cause skin reactions.
- Pregnancy and nursing. Many aromatherapy organizations advise talking to a doctor or midwife before using essential oils during pregnancy.
- Babies and young children. Keep oils out of reach and avoid direct application to babies.
- Pets. Linalool-rich oils can still be a concern for cats. Keep diffusers where animals can leave, and read our guide to essential oils and pets first.
- Medicines and conditions. Ask your healthcare provider if you have asthma, epilepsy or a skin condition, or if you take prescription drugs.
Choosing a Good Ho Wood Oil
- Look for the botanical name and chemotype: Cinnamomum camphora ct. linalool.
- Check the plant part: wood, leaf or leaf and twig.
- Look at the country of origin and the distillation method, which should be steam distillation.
- Choose dark glass bottles with tamper-evident seals.
- Be careful with very cheap or vague products. “Ho wood fragrance oil” is usually synthetic, and “camphor” on its own is not what you want.
- Ask for a GC/MS report if the seller offers one, but remember that a report does not prove safety by itself.

Storage and Shelf Life
Keep the bottle tightly closed, upright and away from heat and light. Linalool-rich oils tend to keep reasonably well, often for a year or two, but they oxidize with age and air. Write the purchase date on the bottle, and replace the oil if it smells sharp, sour or flat.
A Note on the Camphor Laurel Tree
The camphor laurel tree is large, long-lived and handsome, and it has been grown as a shade and ornamental tree in many countries. It is also considered an invasive species in some regions, including parts of eastern Australia and the southeastern United States, where it spreads readily and can crowd out native plants. For that reason, using the tree for oil production, especially from leaves and twigs, is sometimes seen as a practical use of a plentiful resource. If you grow or find camphor laurel, do not use the plant material at home for oil or tea. The chemistry varies from tree to tree, and some chemotypes contain hazardous compounds.
