Rating (out of 5): 2

Arnica, particularly Arnica montana, has a long history of traditional use for the treatment of bites and stings, especially in European herbal medicine. Its primary application has been as a topical remedy, believed to reduce pain, swelling, and inflammation associated with insect bites and minor injuries. The main constituents thought to contribute to these effects are sesquiterpene lactones, flavonoids, and essential oils, which have been shown in some laboratory studies to have anti-inflammatory and analgesic properties.

However, scientific evidence specifically evaluating the efficacy of arnica for bites and stings is limited and of low quality. Most clinical studies on arnica focus on its use for bruises, sprains, or osteoarthritis, with mixed results. There is little to no robust clinical research directly supporting its use for insect bites or stings in humans. Topical arnica is widely used in folk medicine, but adverse reactions such as skin irritation or allergic contact dermatitis are possible, and it should not be applied to broken skin.

In summary, the use of arnica for bites and stings is primarily justified by tradition and anecdotal reports rather than strong scientific validation. While its anti-inflammatory properties are plausible, high-quality clinical trials are lacking for this specific indication.
