Peppermint oilCAS NO8006-90-4 A colorless or pale yellow clear liquid with a special cool fragrance; initially pungent and then cooling in taste. Over time, the color gradually darkens. It can be freely mixed with ethanol, chloroform, or ether. The relative density should be 0.888 to 0.908 (Appendix VII A). The optical rotation, determined according to specified methods (Appendix VII E), should be between -17° and -24°. The refractive index should be 1.456 to 1.466 (Appendix VII F). The molecular weight is 153.27, and the melting point is 42-44°C.
Peppermint oilCAS NO8006-90-4 Menthol oil is a colorless or pale yellow clear liquid with a special cool fragrance. It initially tastes pungent and then cooling. It is used as an aromatic, flavoring, and anti-wind medicine. It can create a cooling sensation on the skin or mucous membranes to alleviate discomfort and pain. Additionally, it helps to soothe liver qi stagnation and promote bile secretion. It is mainly used for chronic calculous cholecystitis, chronic cholecystitis, and bile stones caused by liver depression and damp-heat stomach stagnation.

star Anise oil trans-anethole CAS NO.8007-70-3 Star anise oil is a colorless to pale yellow liquid with a relative density of 0.979 to 0.987 and a refractive index of 1.552 to 1.556. It often becomes cloudy or crystallizes when cold but clears up upon heating. It is easily soluble in 90% ethanol. It has a fragrance reminiscent of anise, licorice, and star anise brain, with a sweet taste.
Gralic oil Allicin35%~55% CAS NO.8008-99-9 A volatile liquid ranging from pale yellow to reddish-brown, with a strong garlic odor. It is insoluble in water, glycerin, and propylene glycol, with a relative density of 1.050-1.059 and a refractive index of 1.550-1.580. Its chemical properties are relatively stable, but it easily decomposes when exposed to alkali.
