According to a study published by "Natural product research", Dracocephalum heterophyllum Benth is used as a Tibetan medicine. The essential oil obtained from the plant via hydrodistillation resulted in a 0.7% (v/w) yield. Analysis identified 83 compounds constituting approximately 89.83% of the total oil, including Cineole at 14.89%, trans-nerolido at 7.10%, and Germacrene-D at 4.84%. The oil's antimicrobial activity was tested against 9 bacterial, 1 yeast, and 3 fungi strains, showing maximal inhibition zones of 18-25 mm for bacteria, 20 mm for yeast, and 8-24 mm for fungi. Additionally, the oil showed a 59.3% inhibition of lipid peroxidation at a concentration of 0.5 mg mL(-1).
