Boxwood comb and horn comb are both good combs. Boxwood is nicknamed Millennium Short, which means that it is not high for a thousand years, and the material is exquisite. Boxwood, like buffalo horn, is also a commonly used Chinese medicine. Its leaves and bark contain buxus, which can inhibit the propagation of fungi and have a certain effect on dandruff removal, but both of them are false. Boxwood counterfeiters are "boxwood" or "tea". Boxwood with a diameter of more than 18 cm is very rare, even less than lobular rosewood. Changzhou White Elephant Boxwood is genuine, worth 400-about 600 yuan and 20 yuan. As a medicinal material, only buffalo horn is a traditional Chinese medicine, which is a substitute for rhinoceros horn. The best horn is rhinoceros horn, which is nearly 400,000 yuan per kilogram. Other horns, such as yellow horn, yak horn and ox horn, are not used as medicine.
