Rating (out of 5): 1

Rhododendron species have a long history of use in traditional medicine systems, particularly in regions such as the Himalayas, China, and parts of Europe. Folk remedies have used various parts of the Rhododendron plant—most commonly the leaves and flowers—to address inflammatory skin conditions, including rashes and hives. The rationale for these uses is based on the plant's purported anti-inflammatory and soothing properties, as described in ethnobotanical literature and traditional healing practices. However, there is very limited scientific evidence to substantiate these uses. Most modern pharmacological research on Rhododendron focuses on its antioxidant or anti-inflammatory effects in vitro or in animal models, and these studies rarely address dermatological applications specifically.

In addition, Rhododendron species contain potentially toxic compounds (such as grayanotoxins), raising concerns about safety, especially when used topically or internally without proper processing. No robust clinical trials or well-designed studies have directly evaluated the efficacy of Rhododendron for treating rashes or hives in humans. Therefore, while traditional use exists, scientific support is lacking, and caution is advised due to potential toxicity.
