Yarrow (Achillea millefolium) has a long history of traditional use in herbal medicine, but its direct support for the Sympathetic Nervous System (SNS) is not well documented in scientific literature. Traditionally, yarrow has been used for its anti-inflammatory, antispasmodic, and wound-healing properties. In folk medicine, it is sometimes employed to address conditions related to stress and anxiety, which can indirectly involve the SNS, as this system mediates the "fight or flight" response. However, there is sparse traditional documentation specifically linking yarrow to the modulation or support of the SNS itself. Most traditional uses focus on digestive, circulatory, and wound-healing benefits rather than direct nervous system effects. Scientific studies on yarrow have mainly explored its anti-inflammatory, antispasmodic, and antioxidant activities, with some supporting its use for wound healing and gastrointestinal complaints. There is limited research on its neuroactive effects, and virtually none that directly connect yarrow to the regulation or support of the SNS. Therefore, while yarrow is a valued traditional herb, its use for supporting the Sympathetic Nervous System is primarily based on traditional herbal concepts rather than robust scientific or even specifically traditional evidence for this particular application.
