Yes Fuyan Pill can cure not only tubal blockage and hydrosalpinx, it cures tubal adhesions as well.
As tubal adhesion is often a result of PID, Fuyan Pill can treat PID and adhesion at the same time. It can promote blood and Qi circulation to treat possible pain which may be induced by adhesions. It can also dissipate hard lumps and dissovle them. Fuyan Pill contains as much as 50 kinds of herbs and each of the ingredients has its unique function in curing the condition. It's a natural treatment, so it brings no side effect.
If you're interested in trying herbal medicine I'd like to recommend 3 months medication with Fuyan Pill.
