Our junior parasite tincture is for ages 2+. It is formulated to be gentle but still aid in parasite detoxing. 
Children do not need as strong of a detox as adults. The body itself is built to detox toxins. As we get older the pathways in our body become backed up.
Because children are active, have generally better diets, less stress, more sleep, they do not need a strong detox. Do not let a company convince you otherwise. The few herbs that are in this detox are PLENTY to aid in parasite detox. Be aware of allergies, you can test it topically.
