I am very toxic from parsites and have them head to toe. I know my blood is toxic and is not cleaning or cleansing very well.I bite on some garlic or cayenne and immediately teh blood rushes to the scalp and feet and other less blood infused areas giving off a buzzing feeling and showing how clogged teh lymph is. So if you are toxic or want to know try that and see if you might get a headache and or itching in areas you suspect parasites to be. If tissues are sore after this or areas are itchy I would say you have damage and or sluggish blood flow. Take this into account as you are cleansing and notice things like this. Document them. I know the liver and kidneys and bowels allneed to be able to keep up so take care what you eat and cleanse at a pace you can handle. Overdoing it really is bad.
