The use of Calamus rhizome (Acorus calamus) for treating or supporting the healing of boils is primarily based on traditional medicine practices. In Ayurvedic and some folk medicine systems, Calamus rhizome has been used for a variety of ailments, including skin conditions such as boils, wounds, and ulcers. This traditional use is thought to stem from the plant’s reputed antimicrobial, anti-inflammatory, and soothing properties, though these are mostly anecdotal and not rigorously documented for this specific application.

Scientifically, there is limited evidence supporting the efficacy of Calamus rhizome specifically for boils. Some in vitro studies have shown that extracts from Acorus calamus possess antimicrobial activity against certain bacteria, which could theoretically be relevant to skin infections like boils. However, these findings have not been robustly translated into clinical studies or validated for the treatment of boils in humans. The evidence for its use in this context remains insufficient, and safety concerns regarding beta-asarone, a compound found in Calamus, further limit its recommendation for therapeutic use. Thus, while traditional practices exist, scientific validation is minimal.
