Do raspberry leaf and rutin effectively relieve glaucoma?
A. Glaucoma is increased pressure in the eye (intraocular pressure) that results from a buildup of fluid called aqueous humor. Chronic glaucoma, as opposed to acute glaucoma, is a common problem in older people and often goes undetected because it has few symptoms. Left untreated, however, this pressure buildup can lead to vision loss and blindness. One underlying cause of chronic glaucoma may be a decrease in the eye’s collagen network. Certain types of collagen make up structural components in the eye and maintaining their integrity may be important. Bioflavonoids, such as rutin from citrus, can strengthen and improve collagen integrity, so there is some theoretical basis for rutin’s use.6 I have not seen any studies on raspberry leaf, but another berry, European bilberry (Vaccinium myrtillus), may be of some help because of its high flavonoid content. I am unaware, however, of any recent literature on preventing or treating chronic glaucoma with these flavonoids. Although flavonoid
