Too my knowledge, this is not true at all. There are a great many other things that will work as a fibrosis, and you should be able too find them at any medical sight, and also at any sight that sells herbal supplements, but always check with a doctor first.
While Red raspberry leaves have many benefits they have not been proven to either help or harm fibroids, always consult with your doctor before taking any medications.
Red raspberry leaves will serve as a natural iron supplement, helping to strengthen your uterine wall muscles. Stronger wall muscles mean it's harder for fibroids to grow. Three or four cups of tea made with raspberry leaves per day should help.
