Witch hazel (astringent)


Witch hazel is an astringent compound produced from the leaves and bark of the North American witch-hazel shrub, (Hamamelis virginiana). It is a component of many commercial healthcare products.

The main constituents of the witch hazel extract include calcium oxalate, gallotannins, safrole, as well as chemicals found in the essential oil (carvacrol, eugenol).

Witch hazel is mainly used externally on hemorrhoids, minor bleeding, and skin irritation. It is often used as a natural remedy for psoriasis and eczema; in aftershave and in-grown nail applications and to prevent facial sweating and cracked/blistered skin, and for treating insect bites, poison ivy, and hemorrhoids. However, clinical studies supporting its effectiveness for these skin conditions are generally lacking.

It is recommended to women to reduce swelling and soothe wounds resulting from childbirth.

Evidence is lacking for further reported uses including gastrointestinal maladies (diarrhea, coughing up/vomiting blood), general infections such as colds and the specific infection tuberculosis, as well as eye inflammation, bruising, and varicose veins.

Native Americans used extract of witch-hazel extensively for medicinal purposes. Many people produced witch hazel extract by boiling the stems of the shrub and producing a decoction, which was used to treat swellings, inflammations, and tumors. Early Puritan settlers in New England adopted this remedy from the natives, and its use became widely established in the United States.
