China's drug regulator approved changes to a supplementary drug application for a mouthwash spray made by Guangzhou Baiyunshan Pharmaceutical (SHA:600332, HKG:0874) subsidiary Baiyunshan Hejigong Pharmaceutical Factory.
The company said 1 milliliter of the product is equivalent to 240 milligrams of medicinal slices containing 13 milligrams of menthol and 2.5 microliters of eucalyptus oil.
The spray is used for mouth ulcers, gingivitis, and sore throat, the filing said.
