The clinical studies for UC were done with qingdai, not a formula. Qingdai is a chinese herb, but the mechanism of action for treating UC is not rooted in Chinese medicine. It's a plant, from the ground, with a specific mechanism of action that helps UC. If a clinical study comes out that demonstrates that it works better in a formula, I'm all ears.
Most likely the study would need to be done for each individual herb, then mixed as a formula and compared. That's not to say the other herbs in the formula aren't good for me, but as it stands qingdai is the one that has been proven scientifically to treat UC, not the other herbs. I'll go with science first.
Most people don't want to spend the time and money to go to a TCM doctor and get a formula that's as inexpensive as qingdai on it's own which they can order with a few mouse clicks, which is why I recommend people start with qingdai so they can stick with it for a while without breaking the bank.
The same philosophy of not sticking with the same thing forever would then have to be applied to medications. Try telling that to someone with chronic UC. Most doctors do not recommend stopping maintenance medication for any length of time. Since I've stopped taking medication completely I have to be extra careful with stopping my alternatives.
