Devil's tongue
Amorphophallus konjac
Amorphophallus konjac, a plant native to East Asia, is traditionally used in some folk remedies but lacks extensive documented use. Scientific evidence suggests that KūlarisTM, derived from Amorphophallus konjac, may reduce acne severity and improve quality of life for individuals with mild-to-severe acne; however, the strength of this evidence is moderate due to limited studies. Additionally, research indicates that certain compounds in AkNBS-LRR43 and AkNBS-LRR100 from Amorphophallus konjac can enhance immune response against bacteria by boosting antioxidant activity. Furthermore, konjac petroleum ether extract has shown potential in inhibiting the migration and invasion of triple-negative breast cancer cells through modulation of OLFML2A to inhibit epithelial-to-mesenchymal transition (EMT). Notably, no major safety concerns or drug interactions have been recorded for Amorphophallus konjac.

What the science says
- AkNBS-LRR43 and AkNBS-LRR100 positively regulate immunity in Amorphophallus konjac against Pectobacterium carotovorum subsp. carotovorum by enhancing antioxidant activity.
- Konjac petroleum ether extract inhibits triple-negative breast cancer cell migration and invasion by modulating OLFML2A to inhibit EMT.
- This study identified 11 AkLOX family members in Amorphophallus konjac and found their expression patterns under various stresses.
- Kūlaris significantly reduced acne severity and counts, improved quality of life, and was well-tolerated in subjects with mild-to-severe acne.
