"Honestly, I dont' even know if I do have overgrowth of candida or not,"

It is usually determined by symptoms. Some might be jock itch or female yeast infection, a great craving for carbohydrates, feeling worse after eating plenty of carbohydrates, excessive flatulence, sensivity to perfumes, cigarette smoke, diesel fumes, etc. There are some websites that have questionaires to help determine if a person has candida overgrowth.

"About the parasite cleanse, a frequent moving bowel is a must. That is why I also do a bowel cleanse together with the parasite cleanse."

The parasite cleanses usually have wormwood, black walnut green hull extract, and cloves. The black walnut itself is a mild laxative, and some parasite cleanses also have other herbs that have a laxative effect. Beware of senna, buckthorn, aloe, rhubarb and other herbs that contain anthraquinones. These can cause rebound constipation, and can be dangerous with long term use. You could use 2 or 3 cups a day of licorice root tea, and plenty of ginger instead. These herbs are much much mild, and are much safer. Olive oil and coconut oil are also mild laxatives. Coconut oil also has antifungal and antiparasitic activity.
Also beware of products that have psyllium or guar gum. Some people get dangerously clogged up with these, especially if they don't drink enough water with them.
