Composition of Extract, and Uses
The main constituents of the witch hazel extract include tannins, gallic acid, phenolics such as catechins, proanthocyanins, flavonoids (kaempferol, quercetin), as well as essential oils (carvacrol, eugenol, hexenol), choline, and saponins. Distilled witch hazel sold in drug stores and pharmacies typically contains no tannin. Witch hazel is mainly used externally on sores, bruises, and swelling, and witch hazel hydrosol is used in skin care (e.g., as an astringent and anti-oxidant potentially useful in fighting acne). It is often also 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, with evidence lacking for further reported uses including GI maladies (diarrhea, coughing up/vomiting blood), general infections such colds and the specific infection tuberculosis, as well as eye inflammation, bruising, and varicose veins. It is found in numerous over-the-counter hemorrhoid preparations. It is recommended to women to reduce swelling and soothe wounds resulting from childbirth.
The essential oil of witch hazel is not sold separately as a consumer product. The plant does not produce enough essential oil to make production viable. However, there are various distillates of witch hazel (called hydrosols or hydrolats) that are gentler than the "drug store" witch hazel.

Famous quotes containing the words composition of and/or composition:
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
“The naive notion that a mother naturally acquires the complex skills of childrearing simply because she has given birth now seems as absurd to me as enrolling in a nine-month class in composition and imagining that at the end of the course you are now prepared to begin writing War and Peace.”
—Mary Kay Blakely (20th century)
