First of all, we should know the specific function of wheat seedling juice. I don't rule out that there are many words exaggerating the function of wheat seedling juice on the Internet, but it is undeniable that wheat seedling juice does have many unique places in assisting human health.
The main functions of wheat seedling juice are as follows: "Wheat seedling is pungent, cold and nontoxic, and it is mainly used to eliminate alcohol toxicity, sudden heat, jaundice and yellow eyes, and pounded juice is beneficial to small intestine ...". (Excerpted from Compendium of Materia Medica), so you asked the answer to this question. Compendium of Materia Medica has already told you.
However, I asked my customer before what she had learned from drinking wheat seedling juice. She told me that it is best to drink it before or after meals 1 to 2 hours, just like drinking tea, which is very good for clearing the heart. The picture I just opened in Taobao has an answer, and the shop is "diligent and plant protection".
I hope it helps you.
