I have no evidence at this time suggesting whether or not rutin is effective at preventing pregnancy other than what is written in Susun's book.
Susun writes "Rutin - Occurring naturally in association with Vitamin c in many plant leaves, most notably Rue, buckwheat, and Elder, rutin can be used to prevent pregnancy. Take it as a tablet in doses of at least 500 mg daily for several days preceding and following ovulation, or take it after fertilizing intercourse and continue until the menstrual flow begins."3
Uni Tiamat writes in her book, Herbal Abortion "Rutin is also known to have the power to prevent pregnancy. In large doses, rutin prolongs the action of the adrenal hormone adrenaline and decreases capillary permeability in the uterine tissues.14 Decreased capillary permeability in the uterine tissues causes the endometrium to become non-nutritive to the fertilized egg. The egg does not implant and abortion occurs."
Rutin is a bioflavinoid, its main function in the body is to help the body strengthen arteries and veins and harden bones and teeth. Some of you have contacted me questioning why Rutin a bioflavinoid can be used to prevent pregnancy, when vitamin c should be used without bioflavinoids. There are still many questions, and I don't have an explanation other than there are different types of bioflavinoids. One of my sources that suggest vitamin c for terminating pregnancy states that it doesn't matter if the vitamin c has bioflavinoids, while others say it should be pure ascorbic acid. And in my studies I have come across references to bioflavinoids having the ability to protect against miscarriage. I've only done a small amount of research on bioflavinoids and have found that there are several different kinds of bioflavinoids, so it may be that certain kinds have different effects.
Cautions for Rutin:
A potential side effect of using rutin capsules in this manner may make one feel anxious or fearful due to its effect of keeping adrenaline in the bloodstream.
