Kalawalla is the brand name of an herbal supplement derived from a type of fern native to Central and South America.
Unsupported claims about the remedial effects of Kalawalla in the treatment of multiple sclerosis suggest that its anti-inflammatory and antioxidant properties regulate the immune system. However, such claims need to be treated with caution as there is no research evidence supporting the use of Kalawalla in MS.
The active ingredient of Kalawalla is Polypodium leucotomos. Where Polypodium leucotomos has been the subject of research studies, the focus has been on the photoprotective properties of the substance and its usage in the treatment of various skin complaints such as psoriasis and light sensitivity.
The risks and benefits associated with the use of Kalawalla in MS have not been fully evaluated.
