Overview Information

Laurelwood is a plant. The nut and other plant parts are used to make medicine.

Don’t confuse laurelwood (Calophyllum inophyllum) with blue cohosh (Caulophyllum thalictroides).

Laurelwood is used for leprosy, hemorrhoids, scabies, gonorrhea, vaginal infections, and chicken pox.

One of the chemicals in laurelwood (constituent (+)-calanolide A) is used for HIV infection. A pharmaceutical company is currently testing this chemical to see if it meets standards of safety and effectiveness that will qualify it for sale as a prescription drug.

Tamanu oil from the nut of laurelwood is used for skin conditions including sunburn, rashes, burns, psoriasis, dermatitis, scratches, skin blemishes, acne, skin allergies, bedsores, rosacea, and hemorrhoids; and for infant skin care.

How does it work?

Laurelwood contains compounds that have been tested in the laboratory and seem to be somewhat effective against HIV and tuberculosis. However, there isn’t enough evidence to know if laurelwood works for medicinal uses in humans.


Uses & Effectiveness?

Insufficient Evidence for

TAKEN BY MOUTH APPLIED TO THE SKIN More evidence is needed to rate the effectiveness of laurelwood for these uses.

Side Effects

Side Effects & Safety

There isn't enough information to know if laurelwood is safe.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking laurelwood if you are pregnant or breast-feeding. Stay on the safe side and avoid use.



We currently have no information for LAURELWOOD Interactions.



The appropriate dose of laurelwood depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for laurelwood. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
