The Graduate School of Biosphere Sciences at Hiroshima University in Japan said that the researchers of the institute and a company in Tokyo have jointly confirmed that the persimmon has a strong anti-norovirus effect.
Norovirus is a calicivirus, which is highly contagious. It can breed in the small intestine after infecting humans and can cause acute gastroenteritis. Patients usually have severe abdominal pain, diarrhea and vomiting. Although the disease is rare, there is no effective treatment other than water and rest. Prevention of noroviruses such as sodium hypochlorite and other chlorine bleaching agents, iodine agents, etc., but these disinfectants have certain side effects on the human body, there is an urgent need for a safe and effective antiviral substance.
Since there are no model animals or culture cell lines that have been previously developed to study the proliferation of Norovirus, a disinfectant for this virus has been developed, and only a cat calicivirus similar to its affinity can be used. This time, Japanese researchers extracted Norovirus from patients with gastroenteritis, and used the reverse transcriptase polymerase chain reaction technology to determine the viral genome to measure the effect of antiviral substances by using the disappearance of the viral genome. The results showed that persimmon can effectively eliminate more than 99% of Norovirus genes.
Persimmon is a persimmon that can not be naturally dislocated and must be artificially dislocated after harvesting. It has been used in traditional Chinese medicine and Japanese folk medicine since ancient times, and it is expected to extract active ingredients against Norovirus.
