2. Polygonum multiflorum can't be eaten casually.
Mr. Liang, 45, unconsciously contracted "frost" on his temples, and even began to have slight baldness. It is said that Polygonum multiflorum Thunb can blacken hair and help hair regeneration. Mr. Liang did not hesitate to start making tea with Polygonum multiflorum Thunb every day. Who knows that a month later, the hair didn't turn black, but the face turned yellow first, and there were symptoms such as loss of appetite, bloating, general fatigue and yellow urine.
Polygonum multiflorum Thunb. Black hair hurts the liver easily.
Mr. Liang was sent to Hankou Hospital by his family. After examination, it was found that Mr. Liang's liver function was seriously damaged, and he was finally diagnosed as drug-induced liver injury caused by Polygonum multiflorum Thunb. Zhang Jinhua, director of the Department of Gastroenterology, said that Polygonum multiflorum Thunb contains a variety of chemical components, which may form toxic compounds on the liver during liver metabolism, thus causing liver damage, resulting in increased transaminase and bilirubin, and a series of clinical symptoms such as jaundice, fatigue, abdominal distension and anorexia, so Polygonum multiflorum Thunb should not be taken at will.
Most products that blacken hair have no effect.
At present, the medical community is not clear about the causes of baldness, but most baldness belongs to congenital factors and has a genetic background. Professor Sun from the Institute of Dermatology, China Academy of Medical Sciences said that hair loss is mainly due to the disorder of melanin synthesis, that is, the melanin synthesis in hair is reduced, and after the black cells in hair matrix cells are reduced, the hair turns white.
Cui Bingnan, deputy chief physician of dermatology, Guang 'anmen Hospital, Chinese Academy of Traditional Chinese Medicine, also said that most of the obvious baldness is related to physique, which is a problem of pigment cells. Traditional Chinese medicine believes that blood heat, kidney qi weakness and qi and blood weakness are all causes of white hair.
Experts believe that the common products that blacken hair on the market are not credible. Because baldness is mostly related to heredity, objectively speaking, there is no medicine that can be absolutely cured at present, so "hair turns black after taking it" is suspected of exaggeration.
In addition, some products that blacken hair contain Polygonum multiflorum Thunb. Cui Bingnan reminded that raw Polygonum multiflorum Thunb, in particular, contains anthraquinone derivative chrysophanol, which is toxic to the body, can damage the liver and stimulate intestinal congestion. Reckless abuse may be counterproductive. If you want to receive treatment, you must go to a regular hospital and take medicine under the guidance of a doctor.
Experts suggest that even if your hair is gray, you don't have to pay too much attention. You need to adjust your mentality. If you are really uncomfortable, you can dye your hair black. In addition, hair has a great relationship with sleep, so young patients should stay up late less and keep regular sleep. In addition, mental stress can easily lead to gray hair, so young people should relax and maintain a good mental state.
