However, chronic inflammation is thought to play a central role in the development of certain diseases ().

Witch hazel contains many compounds with potent anti-inflammatory properties, including gallic acid and tannins.

It also contains antioxidants that help prevent widespread inflammation and neutralize free radicals, which are disease-causing compounds that can build up in your body (, ).

Therefore, witch hazel could have far-reaching benefits and may be useful in the treatment of inflammatory-related issues, such as acne, eczema or psoriasis.

Studies show that topically-applied witch hazel can effectively reduce inflammation and help soothe your skin (, ).

Some research suggests that applying witch hazel topically to sensitive skin may be beneficial in the treatment of inflamed, irritated or broken skin.

In fact, witch hazel has been shown to suppress erythema — a reddening of the skin caused by injury or irritation — by up to 27% ().

One study in 40 people found that using a lotion with as little as 10% witch hazel extract was effective in reducing skin inflammation and treating erythema ().

Hemorrhoids are caused by the swelling and inflammation of the veins in your rectum and anus, resulting in symptoms, such as constipation, itchiness and bleeding.

Witch hazel is often used as a natural remedy to provide relief from the discomfort and pain caused by hemorrhoids.

It’s typically added to a cloth or cotton ball and applied directly to the affected area to soothe the skin.

Though research is limited, witch hazel is believed to help treat the itching, redness, pain and swelling associated with hemorrhoids due to its anti-inflammatory effects ().

What’s more, it has hemostatic properties, meaning that it may stop bleeding caused by hemorrhoids ().

Summary Witch hazel is often used to reduce the itching, redness, pain, bleeding and swelling associated with hemorrhoids. More studies are needed to evaluate its effectiveness.

Thanks to its powerful anti-inflammatory properties, some research suggests that witch hazel could be useful in the treatment of acne.

It can be applied directly to your face after cleansing or steaming for maximum effectiveness.

It acts as an astringent, causing your tissues to contract to help shrink pores, while also soothing your skin and relieving inflammation ().

This may prevent acne-causing bacteria from entering your pores. For this reason, witch hazel is commonly added to many over-the-counter acne products and is especially useful for individuals with oily skin.

Still, studies on the effects of witch hazel on acne are limited and further research is needed to determine its efficacy.

Summary Witch hazel may help reduce scalp irritation and inflammation. It’s also sometimes used for treating dandruff and dryness, though more studies are needed to evaluate its effectiveness for these conditions.

Because of its ability to decrease inflammation and act as an astringent, witch hazel is sometimes used to treat sore throats.

Boiling one teaspoon (5 ml) of witch hazel in one cup (240 ml) of water for about 10 minutes, then gargling with the mixture, may provide relief.

This is believed to help reduce swelling, decrease pain and dry excess mucus caused by a sore throat.

Yet, even though the anti-inflammatory properties of witch hazel are well documented, its use for treating sore throats is based solely on anecdotal evidence.

More high-quality studies are needed to ascertain the potential benefits of witch hazel on sore throats.

In addition, taking witch hazel orally may cause stomach irritation due to its high tannin content, so it’s important to proceed with caution and consult your doctor if you have any concerns.

Summary Witch hazel is often used as a natural remedy for sore throats, but additional studies are needed to look at its potential benefits and side effects.

One animal study found that tannins can act as a barrier, preventing inflammation-causing substances from entering your skin cells ().

What’s more, a test-tube study showed that witch hazel helped neutralize harmful free radicals and prevented the spread of skin cancer cells ().

Similarly, another animal study discovered that the tannins in witch hazel were able to slow skin tumor growth in mice exposed to radiation ().

More studies are needed to look at the effects of witch hazel and its potential impact on viral infections in healthy adults.

Summary Test-tube studies show that witch hazel may have antiviral properties and could be useful against certain types of viral infections.

Most people can use witch hazel safely with minimal risk of adverse side effects ().

Ointments and extracts can be applied directly to your skin several times per day and safely administered for the treatment of hemorrhoids after each bowel movement.

Doing an initial skin patch test on a small portion of your skin can help prevent unwanted side effects and skin reactions.

Additionally, while taking 3–4 teaspoons (15–20 ml) of witch hazel per day is generally considered safe, ingesting large amounts may cause stomach irritation and vomiting ().
