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.

“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
“If I don’t write to empty my mind, I go mad. As to that regular, uninterrupted love of writing ... I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.”
—George Gordon Noel Byron (1788–1824)
