Ayurvedic Climbing Plant with a Medicinal Tradition
The Indian woodrose (Argyreia nervosa var. speciosa) is a vigorous tropical climber of great significance in traditional Ayurvedic herbal medicine. Unlike the Hawaiian variety, it contains significantly lower levels of psychoactive alkaloids and is therefore primarily valued for its medicinal properties.
For centuries, its roots, leaves, and seeds have been used in Ayurvedic medicine. The root in particular is considered a key component in classical formulations used to treat erectile dysfunction, diabetes, bronchitis, and other chronic ailments. In India, the plant is not only appreciated for its therapeutic qualities but is also cultivated as an ornamental feature.
It produces large, velvety leaves and trumpet-shaped flowers with an exotic appearance – a true eye-catcher for greenhouses or conservatories.
Note on varietal selection:
Within the species Argyreia nervosa, two varieties are occasionally distinguished: var. nervosa and var. speciosa.
While var. nervosa represents the classic form with smaller flowers, var. speciosa is notable for its particularly large and decorative blooms.
It is also reported that the seeds of both forms may differ in their content of naturally occurring alkaloids.
For instance, var. nervosa is often attributed with a higher content of ergoline alkaloids (e.g., lysergic acid amide, LSA), whereas var. speciosa is considered comparatively low in alkaloids.
These claims are based on anecdotal evidence and are not scientifically verified. Actual composition may vary depending on origin and cultivation.
This distinction is primarily of horticultural, ornamental, or collector’s interest and is not officially recognised botanically.
