Hello Fiona - Some people see parasites from day 1 on HUMAWORM. It depends on how heavy the infestation is - the types of parasites being removed and the general health of the person cleansing. Young liver flukes will come out before the older, more established ones.
HUMAWORM is a 30 day cleanse - it is formulated to treat the enitre body at the same time - it also catches parasites in all of their life cycles during the continuous 30 day period. Thank you and please keep us posted.
