Traditional Korean medicine diet~~Effect?

I tried traditional Korean medicine dieting in my 20s.

It really kills my appetite when I eat it.

My heart is pounding so much, and my hands are trembling.

I'm trembling, so daily life is quite difficult.

Insomnia comes and makes the next morning very difficult.

My appetite is perfectly fine, but I am experiencing a decline in consciousness.

It used to be a potion back then, but these days it seems to come in capsules too.
