With the Agrisept-L, I would recommend 10-15 drops, 2-3 times a day in water or juice. For severe imbalances, I would use the higher dose. Some people have used 20 drops at a time. Agrisept-L and Morinda both have antiparasitic actions, as well as helping to balance other micro-organisms. Morinda - http://www.chinaphar.com/1671-4083/23/1127.pdf
