Swertia, a genus of plants in the Gentianaceae family (notably Swertia chirayita), has a long history of use in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM). In these traditions, Swertia species are primarily used for their purported effects on liver health, fever reduction, and as general tonics. There are scattered traditional references suggesting the use of Swertia-containing formulas for neurological conditions, including those resembling stroke or post-stroke paralysis, especially in some regional folk medicine practices in Asia. However, these applications are not prominent or well-defined in classical Ayurvedic or TCM texts; rather, they appear in more recent or localized traditions.

From a scientific perspective, there is minimal direct research supporting the use of Swertia for stroke prevention, treatment, or recovery. Some laboratory studies have explored neuroprotective and anti-inflammatory properties of certain compounds found in Swertia, such as swertiamarin and mangiferin, but these studies are preliminary and mostly conducted in vitro or in animal models. No robust clinical trials exist to validate its efficacy for stroke in humans, and standard medical guidelines do not recognize Swertia as a therapy for stroke.

In summary, the use of Swertia for stroke is primarily justified by traditional use, with only minor, indirect scientific rationale. The strength of supporting evidence is weak, and more research is needed before it can be recommended for this purpose.
