Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tannins are a group of polyphenolic compounds found in many plants, and their use in traditional medicine for itching (pruritus) is primarily based on their astringent properties. Traditionally, tannin-rich extracts, such as those from witch hazel, oak bark, or tea, have been applied topically to soothe itching associated with minor skin irritations, insect bites, and rashes. The astringent effect of tannins helps to "tighten" skin and mucous membranes, which can reduce inflammation and provide a temporary barrier effect, thereby relieving some symptoms of itching. Folk medicine practices across various cultures have recommended tannin-containing poultices, washes, and baths for managing pruritic conditions.

From a scientific standpoint, there is limited direct clinical evidence assessing tannins specifically for itching relief. Some laboratory studies suggest that tannins have anti-inflammatory and antimicrobial properties, which may contribute indirectly to alleviating symptoms of itching, especially when related to minor skin irritation or infection. However, robust clinical trials demonstrating their efficacy for pruritus are lacking. As a result, the use of tannins for itching is best characterized as supported by tradition, with a modest evidence rating due to some plausible mechanisms of action but insufficient direct scientific validation.
