Are diet herbal medicines effective?

I'm curious if diet pills are effective.

They say exercise helps as you get older, but the belly fat called "age fat" doesn't seem to go away at all.

Thinking about diet herbal medicine, I'm interested.

I see that everyone around is taking diet herbal medicine and seeing results.

However, there is a concern that herbal medicine may be harmful to the liver, so I am hesitant.

First of all, since it's herbal medicine, I think it will be difficult to take if it's too bitter, and I'm worried about whether I can take it consistently.

Will there still be a rebound even if I lose weight again?

I am curious whether there are people who cannot tolerate it or should avoid it depending on their constitution.
