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 there is no denying 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 non-toxic. It is mainly used to eliminate alcoholism, sudden fever, jaundice and yellow eyes. Pouring 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 client before what she learned from drinking wheat seedling juice. She told me that it is best to drink 1 2 hours before or after meals, just like drinking tea, which is good for clearing the heart. The picture I just opened in Taobao has the answer, and the shop is "diligent plant protection".
I hope it helps you.
