Rhododendron caucasicum has a history of traditional use in folk medicine, particularly in the Caucasus region, where it has been consumed as herbal tea and used in various remedies. The plant has been attributed with a range of health benefits, including cardiovascular support and blood purification, though these claims are largely anecdotal and rooted in regional practices rather than formal scientific validation. Traditionally, some herbalists have used it to support blood circulation and to purportedly “cleanse the blood,” but there are no robust historical texts or pharmacopeias outside of local traditions substantiating its specific use for the blood system.

Current scientific literature on Rhododendron caucasicum is limited, with very few studies exploring its effects on blood or hematological parameters in humans. Some research has investigated antioxidant properties of extracts from Rhododendron species, which theoretically could contribute to vascular health, but there is insufficient evidence to directly link these effects to improvements in blood system function. No clinical trials or peer-reviewed studies have established efficacy or safety for this purpose.

In summary, the use of Rhododendron caucasicum to support the blood body system is primarily justified by traditional use, with little to no scientific validation or high-quality evidence supporting its efficacy for this specific health claim.
