Sorry I had to say something as the advice to stop all herbs is not good advice as many herbs can help your body heal.
The main thing you need to do is do some serious colon cleansing for a few months and cut out all sugars. They are fermenting in your guts and feeding bad bacteria or candida.
Start adding in probiotics and you should start to recover. Anything you try needs to be long term though, your body will take some time to heal. It's not something that will change overnight. Any questions hit me up.
cheers
