Cedar alcohol, extracted from Machilus thunbergii, can nourish scalp hair roots.

Chinese herbal medicine in China has many precious wealth left by ancestors. For example, the Compendium of Materia Medica records many related medicinal materials for treating alopecia, and it has been mentioned that Platycladus orientalis has the effect of treating alopecia. Although there are many related studies abroad, many Chinese herbal medicine extracts have even been developed as "hair care agents" for external use; China Jian 'an Pharmaceutical University's research on "Cell Evaluation of Several Natural Extracts Applied to Male Baldness Care Products" found that the essential oil of Cupressus orientalis really has the function of inhibiting 5α- reductase. Animal experiments also show that Sabina vulgaris essential oil can promote the growth of animal hair.

The bark extract of Phoebe bournei and its components have excellent antioxidant activity or anti-inflammatory ability. In addition to Platycladus orientalis, Dr. Quan said that a Hinokitiol component can also be extracted from the wood of Sabina vulgaris or Phoebe bournei, which has natural disinfection, antibacterial, deodorizing and antiseptic functions. Phoebe bournei in Taiwan Province is one of the endemic native tree species in Taiwan Province Province, belonging to Cupressaceae, growing at an altitude of 800? 1, 500m central mountainous area, with beautiful tree shape, excellent material and natural fragrance. It is often used as a material for furniture, sculpture, architecture and decoration, and is deeply loved by Chinese people. It is listed as a first-class conifer in Taiwan Province Province.

There are many studies on the effect of Chinese herbal medicine extracts on alopecia abroad, and even a "hair tonic" for external use has been developed. (Photo/Huang) Taiwan Province has been studying the chemical constituents of Phoebe bournei for decades. In the early days, it mainly focused on the identification of components. Until recently, there were some reports about its biological activity. It was found that the ethanol extract from the bark of Phoebe bournei had a significant ability to scavenge DPPH free radicals. It turns out that the ethanol extract of Phoebe bournei bark in Taiwan Province is rich in huperzine A, which can effectively inhibit TNF-α and IL- 1 induced by inflammatory substances.

No matter the extracts of Chinese herbal medicines such as Platycladus orientalis, Sabina vulgaris or Phoebe bournei, they will become the further research objects in the future, and even have the opportunity to develop external skin care products that nourish the scalp and hair roots, which is expected to become a new choice to prevent male hair loss in the future.
