Answer:

An xoa (Helicteres hirsuta Lour), also known as to ken long or do long, is a perennial plant commonly found along rivers, streams, or in forests. It has a pungent taste and aromatic scent, and folk medicine traditionally uses it to clear heat, detoxify the liver, and support the treatment of liver diseases.

However, there is currently no specific medicine to eliminate the hepatitis B virus; only drugs to control the viral load are available. The use of an xoa in treating hepatitis B requires a doctor's consultation to avoid complications. There have been cases where hepatitis B patients arbitrarily used an xoa instead of their prescribed treatment regimen, leading to a worsening of their condition, progressing to decompensated cirrhosis and ascites.

The liver is an important organ, performing functions such as bile production, detoxification, and metabolism. Liver diseases, including viral hepatitis, cirrhosis, and liver cancer, cause over 2 million deaths annually worldwide. In Vietnam, about 8-10% of the population is infected with hepatitis B, and the disease can silently progress to chronic. Hepatitis B is transmitted through blood, sexual contact, and from mother to child. The disease often shows no clear symptoms, with many people only discovering it in its late stages.

Since a family member has hepatitis B, those living with and frequently exposed to him should get tested for hepatitis B. If infected, prompt treatment is essential. If not infected, everyone should get vaccinated for active prevention.

Currently, Vietnam offers many types of hepatitis B vaccines for children and adults, including: single-dose vaccines and combination vaccines that also protect against hepatitis A. Newborns should be vaccinated within the first 24 hours after birth, followed by vaccinations according to the 5-in-1 or 6-in-1 schedule. Adults need three doses within 6 months, or four doses for high-risk individuals such as those living with an infected person, after being tested for hepatitis B before vaccination. Booster shots are needed when antibody levels fall below the protective threshold.
