Tree nut allergies are one of the most common and fast-growing types of food allergies in North America today.
When someone with a tree nut allergy ingests their allergen, even a trace amount, that person is at risk of a severe allergic reaction, called anaphylaxis. An anaphylactic reaction includes more than one of the body’s systems, such as the respiratory tract, gastrointestinal tract, the skin and cardiovascular symptom.
In the United States, for food labeling purposes, the FDA considers the following to be tree nuts:
Almond, Beech nuts, Brazil nuts, Butternuts, Cashews, Chestnuts, Chinquapins, Coconuts, Filberts/hazelnuts, Ginko nuts, Hickory nuts, Lichee nuts, Macadmamia nuts/Bush nuts, Pecans, Pine nuts/Pinon nuts, Pistachios, Shea nuts, and Walnuts.
While coconut is considered a tree nut when it comes to food labeling purposes in the United States, it is not, strictly speaking, a nut. Rather, it is the fruit of a palm tree. Most people with tree nut allergies are able to eat coconut. However, it is possible to be allergic to coconut. Always check with an allergist about whether coconut is safe in your diet.
Ingesting and topical applications in cosmetics and personal care products are of course two different things. Cosmetics and personal care products sometimes contain nut oils but these are likely to have been refined.
Almond allergens can be contained in almond oil. Topical application of some oils can sensitize. Although we could not find scientific research indicating any case of anaphylaxis to almond oil via the topical route, we would prefer our customers with known tree nut allergies be safe rather than sorry and avoid these products that contain Sweet Almond Oil:
Shea butter is derived from the seed or kernel from the Shea tree and is very rich in oil. The oil or butter is refined, bleached and deodorized, and the final product is primarily fat rather than protein.
The Food Allergen Labeling and Consumer Protection Act of 2004 requires major allergens to be listed in all packaged goods. The 2006 US Food and Drug Administration guidelines included shea nut among other tree nuts. Shea nut is distantly related to Brazil nut, which cross-reacts with almond, hazelnut, walnut, and peanut. Because of its high content of nonsaponifiable lipids, shea butter is widely used in cosmetic, baby care, food, and confectionary products.
The Journal of Allergy and Clinical Immunology tested Shea butter and found it contains no IgE-binding soluble proteins. There are no reports of ingestion or contact-related reactions to shea butter in individuals with nut allergy.
The fatty content of the shea nut kernel varies by region from 29.7% to 53.7%. The protein content is poorly characterized; in one study, 42 mg protein was extracted from 100 g shea nut (0.042%). For comparison, Brazil nut contains 14% protein, cashew and pistachio 21%, and peanut 25%.

We have found lay articles that indicate people with latex allergies (especially TYPE B latex allergy) may have a reaction to shea butter because it contains natural latex. So if you’re sensitive to latex, then it's possible to react to shea butter overtime."
While any food may cause an allergic reaction, mangoes are unique in that they belong to the plant family that also contains poison oak, poison ivy, and poison sumac. They all contain urushiol, an oil found within the Anacardiaceae plant family. This oil can contact dermatitis. Urushiol is also found in the sap, skin, stem, and leaf of mangos.
It is filled with oleic acid and stearic acid, two fatty acids that work to keep skin soft. The butter is also high in antioxidants and vitamins, and has been touted to have wound healing properties as well. We love it because it helps produce the hardness in our soap bars making it last through dozens of uses while still providing a rich, conditioning lather.
There are essential terms that may help you understand the various body’s response to allergens including overactive sinuses, obstructed airways, digestive problems, or inflamed skin.
