Hello, your disease is generally caused by yin-yang imbalance from the perspective of traditional Chinese medicine. It is very correct to take Kuntai capsule, but everyone's physique is different. How long it takes to take effect depends mainly on your own physique. Generally speaking, it will be effective in about ten days. I suggest you take it for ten days first. If the effect is not good, you can take Gengnian 'an capsule instead, and the effect will be better.
