Are there warnings for tylophora supplements that i should know?

Tylophora: Tylophora is a climbing perennial plant that grows in india. The only available clinical studies [poorly designed ones at that] are using it with asthma. So there's not enough evidence to support its use for other conditions. Reported adverse effects include nausea, vomiting, dizziness, and sedation. Some work is ongoing to investigate possible antispasmodic and anti-ulcerogenic activity.
