Bay Laurel Oil – Possible Skin Issues:
Greener Life Diamond – Bio-Healthy Score => 3: Possible Skin Issues:
Maximum dermal use level: 0.5% to avoid skin sensitization
Tisserand and Young recommend that Bay Laurel oil be limited to 0.5% (about 3 drops per ounce of any other carrier oils) for leave-on products like ointments, creams, and lotions. There is no restriction for body washes, shampoos, soaps, and other wash-off products because the oil does not remain on the skin.
Bay oil is said to exhibit irritation, sensitization, hepatoxicity and cytotoxicity. Topical application and inhalation of this oil might cause allergies, skin irritation, sensitization in pregnant women, children and nursing mothers, arrest blood clotting and irritate the mucous membranes. It is recommended to avoid Bay oil during pregnancy, even in a diluted form, as it may cause harm to the developing fetus.
The key chemical constituents responsible for the possible skin issues of Bay Laurel oil are eugenol and methyleugenol. Although it is an excellent decongestant and antiseptic, eugenol in undiluted Bay oil can cause rashes, itching, irritation of the skin and the mucous membranes, when applied as a decongestant ointment or during inhalation of the concentrated oil. Always dilute Bay Laurel oil with an inert carrier oil and perform a patch test on your skin before using it for dermatological purposes.

Numerous studies state that Bay oil has cytotoxic effects, which means it can be toxic or deadly to cells. For this effect, Bay oil is used therapeutically in Apoptosis or a genetic line up for controlled cell death, especially in the treatment of Cancer. Chemotherapy (treatment of cancer) solely depends upon the potential of cytotoxic remedies to destroy the existing cancerous cells and thwart the rapid reproducing ability of cancer cells (Antiproliferative ability).
According to the European Commission’s scientific committee opinion on Food, Methyleugenol displays genotoxic and carcinogenic effect and should be limited in products that remain on the skin.
Bay Laurel is often confused with other members of the Laurel family like Mountain Laurel, Cherry Laurel, which are potential toxic agents. It is also confused with Westy Indian Bay.
This warning is applicable to direct skin applications like lotions, balms, massage oils and creams and not for bathing products like soaps and shampoos.
