Bryophyllum pinnatum (Lam.) Oken: unravelling therapeutic potential and navigating toxicity.

ABSTRACT

Bryophyllum pinnatum (Lam.) Oken, a multipurpose medicinal herb, has drawn much interest for its therapeutic qualities from both traditional and modern medicine systems. Many active secondary metabolites, such as bufadienolides, triterpenes, phenols, alkaloids, glycosides, lipids, flavonoids, and organic acids, are responsible for the plant's curative properties. B. pinnatum exhibits a noteworthy significance in oncological research by exhibiting its ability to modify numerous pathways, which may suggest a potential anticancer impact. The herb is recommended for treating lithiasis, a common cause of renal failure, due to its effectiveness in dissolving stones and avoiding crystal formation. The plant has a major impact on diabetes, especially type II diabetes. Moreover, the versatility of B. pinnatum extends to its examination in connection to COVID-19. However, caution is warranted, as B. pinnatum has been reported to possess toxicity attributed to the presence of bufadienolides in its metabolic profile. A comprehensive investigation is essential to thoroughly understand and confirm the synthesis of potentially hazardous compounds. This is crucial for minimizing their presence and ensuring the safe consumption of B. pinnatum among diverse populations of organisms. This review highlights the various medical uses of B. pinnatum, including its ability to effectively treat kidney and liver diseases, as well as its anti-leishmanial, neuropharmacological, antibacterial, immunosuppressive, anti-tumour, and cytotoxic effects. While extensively employed in both traditional and scientific domains, the plant's complete medicinal potential, molecular mechanisms, safety profile, and pharmacodynamics remain ambiguous, rendering it an ideal candidate for pioneering research endeavours.
