Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Calamus rhizome (Acorus calamus), also known as sweet flag, has a long history of use in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine. In these traditions, the rhizome has been used for a variety of respiratory complaints, including congestion, coughs, and colds. The rationale for its use is based on its reputed expectorant, bronchodilatory, and anti-inflammatory properties, which are believed to help clear mucus and ease breathing. Traditional texts often include calamus in formulations intended to "open the airways" and "clear phlegm."
However, scientific validation for these uses is minimal. While some animal studies and in vitro experiments have suggested that calamus extracts possess anti-inflammatory and antimicrobial effects, there is little direct clinical evidence supporting its efficacy specifically for respiratory congestion in humans. Most of the support for its use in this context comes from traditional medical literature and anecdotal reports rather than well-designed scientific trials. Additionally, safety concerns exist due to the presence of β-asarone in some calamus varieties, which is potentially carcinogenic.
In summary, the use of calamus rhizome for congestion is primarily justified by traditional use, with a low level of scientific evidence to support its effectiveness for this specific condition.
