Maximum dermal use level: 0.8% to avoid phototoxicity
The International Fragrance Association (IFRA) recommends that Angelica Root oil be limited to 0.8% (about 5 drops per ounce of any other carrier oils) for leave-on products like ointments, creams, and lotions used on skin exposed to sunlight. There is no restriction for body washes, shampoos, soaps, and other wash-off products because the oil does not remain on the skin.

Angelica root oil is said to exhibit phototoxic effects, resulting in irritation of the skin, redness, allergies, sunburns, blisters, hyperpigmentation and photodermatitis or Berloque dermatitis. These skin maladies might occur if your skin is exposed to sunlight after the dermal application of this oil within 12 to 36 hours of usage.
The underlying principle is the reaction of plant furocoumarins or Psoralens present in Angelica Root oil, namely angelicin. This component makes skin more prone to sunburn. Phototoxic, carcinogenic, genotoxic and mutagenic effects all follow from the increased risk of sunburn.
Research reports state that autoxidation components in Angelica root oil like alpha-pinene, limonene and delta-3-carene might cause skin sensitization. Storage of this oil in dark and airtight container, preferably in refrigerator is recommended.
The International Fragrance Association (IFRA) says that the safe level of dilution for the use of Angelica root oil on the skin exposed to sun is 0.8%, which is about 5 drops per ounce of any carrier oils.
Studies suggest that Angelica root oil should be avoided by pregnant and lactating women mainly due to its phototoxic, emmenagogue and abortifacient properties, as it might cause changes in the cellular structure of the fetus, induce menstruation and lessen the supply of milk (anti-galactogogue) in nursing mothers.
A 2011 study on ‘Angelica archangelica’ published in the International Journal of Nutrition, Pharmacology, Neurological Diseases states that this traditional herb can be a potent alternative for producing harmless and effectual anti-cancer drugs.
The most comforting note is that the coumarins are not the major constituents of Angelica root oil, and while caution should be used for leave-on products like lotions and creams, it is generally safe for wash off products like soaps, shampoos, and other bath preparations..
