I am glad that you are feeling better and supported. Yes, I meant N-Acetyl Cysteine. From my readnig it can be taken regularly and has anti parassitic properties as well as a strong anti oxidant. I also take MSM for the same reason. Over the years I have cycled with different anti parastical herbs, mostly garlic, tumeric, ginger.. There are many.. and ofcourse the main three if you are doing a specific parastie cleans are cloves, blackwalnut hulls and Wormwood taken together. If you research Hulda Clarkparasite cleanse.. you can find single products which carry all of these herbs together.
