Arnica has traditionally been used in herbal medicine to treat a variety of skin ailments, including bruises, sprains, muscle soreness, and, occasionally, blisters. The primary rationale behind its use for blisters is its purported anti-inflammatory and analgesic properties, which are believed to reduce pain and swelling associated with minor skin injuries. Historically, arnica preparations—such as creams, ointments, or tinctures—were applied topically to unbroken skin near blisters to ease discomfort and potentially accelerate healing.

However, scientific evidence specifically supporting the use of arnica for blisters is limited. Most clinical research on arnica focuses on its effectiveness for bruising, muscle soreness, or osteoarthritis, rather than on its effects for blisters. Furthermore, because arnica can cause irritation or allergic reactions when applied to broken skin, its direct use on open or burst blisters is not recommended and may worsen the condition. Modern wound care guidelines do not mention arnica as a recommended treatment for blisters, and its use remains rooted in traditional herbal practices rather than in validated clinical protocols.

In summary, while arnica’s use for blisters has traditional roots, there is little scientific evidence to support its effectiveness for this specific condition. Caution is advised, especially when considering application to broken skin.
