Quercetin, a flavonoid with antioxidant and anti-inflammatory activities, contributes to the plant's ability to soothe and calm irritated tissues. Hamamelin, a volatile oil, has antimicrobial and anti-inflammatory effects, while gallic acid, a polyphenol, exhibits antioxidant and anti-inflammatory activities. Hamamelose, a sugar molecule, has been shown to have anti-inflammatory and immunomodulatory effects by inhibiting the production of pro-inflammatory cytokines.

The combination of these constituents in Hamamelis virginiana contributes to its well-documented use in treating skin conditions such as eczema, wounds, and hemorrhoids.

The tincture is a concentrated liquid extract of the plant's leaves and twigs, used to treat wounds, skin irritations, and insect bites due to its astringent, anti-inflammatory, and antimicrobial properties. The salve is a topical application made from the tincture, often combined with other herbs and oils, to provide localized relief for skin conditions such as eczema and minor cuts. The infusion and tea are liquid preparations made by steeping the leaves in hot water, used to treat internal issues like digestive problems, sore throats, and colds, due to the plant's antiseptic and anti-inflammatory properties.

Consuming Hamamelis virginiana can also cause diarrhea, which may exacerbate existing gastrointestinal conditions, such as irritable bowel syndrome or inflammatory bowel disease. Experiencing nausea is another possible side effect, as the plant's anthraquinone content can irritate the digestive system, leading to stomach discomfort and nausea. These side effects occur because Hamamelis virginiana's bioactive compounds interact with the body's physiological processes, affecting blood clotting, gut motility, and stomach pH regulation.

Improper use of Hamamelis virginiana may also mask symptoms of underlying medical conditions, such as bleeding disorders or gastrointestinal diseases, requiring immediate medical attention.
