A gentle astringent for irritated skin, bites and piles
Witch hazel
A gentle plant-based astringent used to soothe minor skin irritation, bruises, bites and piles.
What is Witch hazel?
Witch hazel is a traditional, gentle astringent made from the witch hazel plant, widely sold as distilled witch hazel. Applied to the skin, it has a mild tightening and cooling effect that soothes minor irritation, helps calm bruises and insect bites, and is often used to ease the discomfort and itching of piles (haemorrhoids). It works on the surface of the skin and is not absorbed in any meaningful way, so it is very gentle. It is for minor problems and short-term use; broken or infected skin, severe symptoms, or piles with bleeding or that do not settle should be checked.

What it is
Witch hazel is a plant-based remedy, usually sold as distilled witch hazel liquid, that acts as a mild astringent on the skin. An astringent is something that gently tightens the skin's surface, which can have a soothing, cooling effect. It has long been used for minor skin irritation, to help with bruises and insect bites, and to ease the discomfort of piles, where it appears in some haemorrhoid products. It is applied to the skin, often dabbed on with cotton wool, and is available over the counter. Because it is gentle and works on the surface, it is a popular traditional remedy for everyday minor skin complaints.
How it works
Witch hazel contains natural plant substances called tannins that give it its astringent action. When applied, this gently tightens the surface of the skin and the tiny blood vessels just beneath it, which can reduce a feeling of puffiness, soothe irritation and give a cooling sensation. For bruises and insect bites, this astringent and soothing effect can help ease swelling and discomfort, and for piles it can calm the irritated, itchy area. It works locally where it is applied rather than being taken into the body, which is why its effects are gentle and confined to the skin surface.

Practical use
Good to know
Witch hazel is best thought of as a gentle, soothing remedy for minor, intact skin: it can be dabbed onto irritated skin, bruises or insect bites, or used as directed on piles, but it should not be put on broken, weeping or badly damaged skin. It is for short-term comfort rather than a cure. With piles, simple measures such as plenty of fibre and fluids and not straining matter too, and any rectal bleeding, a noticeable lump, or symptoms that do not settle within a week or so should be checked rather than just treated at home, as bleeding always deserves assessment. It is generally very well tolerated, though occasionally the skin can react to it, in which case stop using it. As with any product, keep it away from the eyes.
Who should not take it / use with caution
- People who have had an allergic reaction to witch hazel should not use it.
- It should not be applied to broken, weeping or badly damaged skin without advice.
- Anyone with rectal bleeding, a lump, or piles that do not settle should seek medical advice rather than only self-treat.
Monitoring
- No routine monitoring is needed.
- Reviewing symptoms if skin irritation or piles do not settle within a week or so.
- Seeking advice promptly for any rectal bleeding or a new lump.
Side effects
- Side effects are uncommon, as it works on the skin's surface.
- Occasionally mild irritation or dryness, especially with frequent use.
- Rarely, an allergic skin reaction, in which case stop using it.
Key interactions
- There are no well-known interactions with medicines taken by mouth, as it acts on the skin.
- Avoid combining it with other strong skin treatments on the same area unless advised.
- Tell your pharmacist about other skin or haemorrhoid products you are using.
Available as: A liquid applied to the skin, and an ingredient in some creams and wipes.
