Clematis vine health benefits
Medicinally clematis and aristolochia manshuriensis are known for their excellent ability on inducing diuresis. That is the exact reason why the latter was heavily adulterated into some diet pills, which thus planted the seeds for the future tragedy. Now we already know that aristolochia plants contain a toxic ingredient called aristolochic acid, which causes human kidney damage or even death in long-term uses. Unlike aristolochia manshuriensis, clematis belongs to Ranunculaceae. That is to say, this herb has the same healing power but without the above-mentioned side effects. As a matter of fact, clematis and akebia quinata are taking over and becoming the substitute in all aristolochia manshuriensis based formulas for the treatment of a variety of diseases, such as Edema, Stranguria, Amenorrhea, arthralgia, oral ulcers, dysfunctional uterine bleeding, excessive vaginal discharge, urinary tract infections, Genital Warts, etc.
