Witch Hazel
Hamamelis virginiana
A plant extract used topically as a natural astringent for skin irritation, hemorrhoids, and minor inflammation. Its tannins tighten tissue and reduce swelling; it is for external use, not ingestion.
What is Witch Hazel?
Witch hazel (Hamamelis virginiana) is a flowering shrub native to North America. Extracts of its bark and leaves — usually sold as a distilled liquid, pad, or ointment — have long been used as a topical astringent for skin care and to soothe irritation, swelling, and minor bleeding. It is one of the few herbal remedies found in mainstream over-the-counter products, particularly for hemorrhoids.
Known Health Benefits
How It Works
Witch hazel's effects come primarily from its high tannin content (including hamamelitannin) and other polyphenols. Tannins are astringents that bind and precipitate proteins, causing tissue to contract and tighten, which reduces swelling, oozing, and minor bleeding and creates a protective barrier over irritated skin. These polyphenols also have antioxidant and anti-inflammatory activity, calming redness and itching. Applied to hemorrhoids or irritated skin, this astringent and anti-inflammatory action relieves discomfort.
What Research Says
Topical witch hazel has reasonable support for skin and mucous-membrane irritation. Studies show witch hazel preparations reduce inflammation and erythema (for example, after UV exposure) and are widely used and recommended for hemorrhoid symptom relief, where its astringent action soothes and reduces swelling. Evidence is strongest for these topical, symptomatic uses; systemic or oral benefits are not established and oral use is discouraged.
Active Compounds
Tannins (hamamelitannin), gallic acid, flavonoids, volatile oils
Forms & Bioavailability
Witch hazel works locally at the site of application; its tannins act on the surface of skin and mucous membranes rather than being absorbed systemically. Alcohol-free distillates are gentler for sensitive or facial skin, while higher-tannin preparations provide a stronger astringent effect.
Dosage Guidance
| Use Case | Dosage |
|---|---|
| Hemorrhoids | Apply medicated pads/ointment after bowel movements |
| Skin irritation / toner | Apply to affected skin as needed |
| Minor inflammation / itching | Apply to intact skin |
Always consult a healthcare provider for personalized dosing.

Topical use is generally very safe; rarely causes skin irritation or allergic contact dermatitis. Oral use can cause stomach upset and is not recommended (tannins and, in some distillates, alcohol).
Who Should Avoid It

Pregnancy & Lactation

Minimal for topical use. Not intended for internal use.
Evidence Classification
Supported by cohort studies, case-control studies, or multiple observational studies with consistent findings.
