Rating (out of 5): 2

Mustard seed has a long history of use in traditional medicine systems, particularly in Ayurveda and traditional European herbalism, to address issues related to poor circulation. Historically, mustard seed has been used both internally (in small amounts as a spice or remedy) and externally (in mustard plasters or poultices). The warming and stimulating properties of mustard seed were believed to enhance blood flow to specific areas, alleviate aches, and counteract cold extremities. Mustard plasters, for example, were commonly applied to the chest or limbs to create localized warmth and increase blood flow, based on the idea that the irritant qualities of mustard stimulate capillaries and improve circulation.

Modern scientific evidence supporting these uses remains limited. Some studies suggest that mustard oil (derived from mustard seeds) can induce vasodilation when applied topically, possibly due to its content of allyl isothiocyanate, which acts as a rubefacient (increases blood flow to the surface of the skin). However, these effects have mostly been observed in animal studies or in vitro, and robust clinical trials in humans are lacking. The oral use of mustard seed for systemic improvement of circulation has not been validated in scientific literature. Therefore, while its use for circulation is rooted in traditional practices, strong scientific validation is currently insufficient, meriting a moderate evidence rating.
