Are herbal medicine remedies at the Korean medicine clinic effective?

This time, I had such severe back pain that I went to a nearby Korean medicine clinic and received acupuncture.

After checking the pulse, he said her energy was too low and advised her to take herbal medicine.

In the past, I just went for treatment, but this time I was really sick and felt so exhausted that I decided to think about it.

But since it's my first time taking herbal medicine, I don't know if it's okay.

I heard that the liver is not good. Is it okay these days?

I wonder if the herbal medicine is effective enough to justify its high price.
