Hi there,
We've had good luck with Xian Fang Huo Ming Yin in rendering the cysts inert and inactive (such that they don't drain anymore). I've never tried Tan Yu Tang. It's another good option. Or you can use both. Often, the cysts persist, but they almost invariably cease to cause the animals problems. So if that's the main goal, you should see success.
All the best,
Steve
