So far, Anoectochilus roxburghii has not been officially recognized as a Chinese herbal medicine, food or health care product, nor is it a new resource food. Therefore, its products cannot pass various corresponding certifications, and generally circulate in the market in the form of primary agricultural products. The market products are chaotic and the supervision and management cannot be standardized. It is best to taste the authenticity, mildew and moderate dryness before buying this kind of products. It is best to freeze them for 1-2 years. If stored at room temperature, it will be damp and moldy in about half a year. I wish you all the happiness in the world.
