(Concern) Herbal medicine diet

I'm 고민이에요.

Now I can't lose weight easily, so I'm even considering herbal medicine dieting.

I hear stories about friends who used traditional Korean medicine for dieting.

My mood is fluctuating.

They say they feel good sometimes but then become depressed, and it repeats?

It's because there are substances similar to narcotics.

Is it really true??

I want to try, but I'm worried ㅠㅠ

Has anyone experienced this through herbal medicine dieting?

Are there any successful people!!
