In the past 20 years, something changed in China, Made in China became low-quality, not safe, it is the truth.
Some business man without conscience made many bad things, it was really shame of China, but everyone can not clare it never happened in your countries. It is only byproduct of rapidly development.
Now we are trying to fix it, although my own strength is little, but I think it will do some effect.

What a shame for me, I exported fenugreek seed extract several tons one year, but I can not say its efficiency immediately.

Have you tried Coptis Root, I think it is more bitter

Although most herbs are bitter, not all herbs are bitter.
There is a Chinese old say: All herbs have toxicity, it means herbs are not suitable to taken daily without docoter's suggestions.
Every herbs has its own characters, it can reslove some problem of our boby, or compounds of herbs can do it, but if you have no problem in your body, I don't think you need to take it.

Valerian officinalis was planted in China in bulk now, the harvest mostly was used to produce Valerian extract, it is a resourse of drugs named Valerian xxx, I think it is easier to buy them instead of plant them buy yourself.
