I have heard mixed reports about colon/parasite/liver cleansing and the like; some say it is hugely beneficial, others say a fraud, down right dangerous and waste of time.
Does the paleo diet (meat/fat) alone provide all the 'inner maintenance' the body needs or is there any evidence that hunter/gathering people internally cleansed their bodies in addition to their diets? If so, how can we replicate this cleanse safely and efficiently with substances readily at our disposal?
