Black Soybean (Hei Dou) 101 Guide: What Is It And Can It Treat Hair Loss?

What is Black Soybean?

Black soybean, also known as "black bean" or "black soy," is a variety of soybean that is commonly used in TCM. It is believed to have a number of health benefits, including improving circulation, reducing inflammation, and promoting healthy hair growth. The beans are typically boiled and consumed as a food, but they can also be ground into a powder and used in a variety of TCM formulas.

How Does Black Soybean Help Treat Hair Loss?

According to TCM principles, hair loss can be caused by a number of factors, including poor blood circulation, hormonal imbalances, and a deficiency in certain nutrients. Black soybean is believed to improve blood circulation and provide the body with the necessary nutrients to promote healthy hair growth. It also contains high levels of protein, which is essential for strong, healthy hair.

One study conducted in China found that black soybean extract was effective in promoting hair growth in mice. The study found that black soybean extract increased the number of hair follicles and the thickness of the hair shafts in mice with hair loss. Another study, published in the Journal of Ethnopharmacology, found that black soybean extract had a positive effect on hair growth in humans.

Black soybean also contains isoflavones, which are a type of phytoestrogen. Phytoestrogens are plant-based compounds that mimic the effects of estrogen in the body. Estrogen is an important hormone that helps regulate the growth and maintenance of hair follicles. By providing the body with phytoestrogens, black soybean may help balance hormones and promote healthy hair growth.

Safety and Side Effects

Black soybean is generally considered safe when consumed as a food or in small amounts as a supplement. However, as with any supplement, it is important to speak with a healthcare provider before starting to use black soybean for hair loss treatment.

Conclusion

Black soybean is a traditional Chinese medicine ingredient that has been used for centuries to promote health and well-being. Its potential hair loss benefits are supported by research, and it appears to be a safe and natural alternative to conventional hair loss treatments. However, more research is needed to confirm these findings, and it is important to talk to a healthcare professional before using black soybean as a hair loss treatment.
