Question 1

How does Agastache rugosa work to relieve digestive symptoms?

Accepted Answer

Agastache rugosa contains volatile oils including methylchavicol, limonene, and beta-caryophyllene, which exert carminative and antispasmodic effects on the digestive tract. In Traditional Chinese Medicine, it is classified as an aromatic dampness-transforming herb, meaning it helps resolve stagnation and promote proper digestive function. The presence of quercetin contributes additional anti-inflammatory activity. These combined actions help relieve nausea, vomiting, and bloating associated with dampness accumulation. Evidence level: C.

Consult a qualified healthcare provider or licensed practitioner of Traditional Chinese Medicine for appropriate alternatives for managing pregnancy-related digestive concerns.
