Preparations
Parts used
Hosta is not mentioned in the provided research abstracts, which focus exclusively on the medicinal interactions between Saussurea root and Corydalis tuber. The study investigates how Saussurea root can augment the pharmacological effects of Corydalis tuber in isolated mouse ileum. Specifically, the researchers observed that Saussurea root increases the depression of acetylcholine-induced contractions when used in combination with Corydalis tuber. The component dehydrocostuslactone was identified as the specific element within the root responsible for this enhancing activity. Ultimately, the investigation aims to clarify the complex modes of action involved in blending these specific crude drugs for medicinal use.
