Ho Wood is a tree quite similar to (or of the same genus as) the camphor tree which is where camphor oil comes from. If you have any experience with the latter, you can already start imagining how Ho Wood oil will smell. Ho Wood oil is also commonly referred to as ‘white camphor’ oil because it is a lighter grade and can be blended more easily
Ho Wood became more popular in 1985 when a major explosion at a linalool-producing facility greatly decreased the available supply, which launched Ho Wood as a natural and sustainable replacement. Locally referred to as Shiu Oil, it is commonly broken for its aromatic constituents.
Ho Wood Oil is steam distilled from the bark and wood of the ho tree. This oil is extremely high in calming linalool and is excellent for promoting a peaceful and relaxing environment. Ho Wood has a woody, floral, and camphorous scent.

Our safety advice
Due to its high safrole content we recommend that brown camphor oil is not used in therapy.
IFRA and the EU recommend a maximum exposure level of 0.01% of safrole from the use of safrole-containing essential oils in cosmetics.
Adverse skin reactions Undiluted brown camphor oil was not irritating to rabbit, pig or mouse skin; tested at 4% on 25 volunteers it was neither irritating nor sensitizing. It is non-phototoxic.
Acute toxicity Brown camphor oil acute oral LD50 in rats 2.53 mL/kg; acute dermal LD50 in rabbits >4 mL/kg
(Opdyke 1976 p. 703). The minimum lethal oral dose of safrole in the rabbit is 1.0 g/kg (Spector 1956).
Carcinogenic/anticarcinogenic potential No information! found. Safrole and its 20,30-epoxy, 10-hydroxy and 10-sulfate metabolites can form adducts with DNA and other macromolecules in the liver, and safrole is a weak carcinogen in rodents. Essential oil profiles C H A P T E R 1 3 227 Humans are at lower risk than rats due to differences in metabolism and more efficient detoxification mechanisms.
Brown camphor oil is not normally available commercially, as it is commonly used for the isolation of safrole or 1,8-cineole. Brown camphor oil is sometimes sold as ‘Chinese sassafras oil’. See comments under Camphor.
