Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
| Used for | Amount | Why |
|---|---|---|
Alzheimer’s Disease | Refer to label instructions |  [2 stars] Lesser periwinkle contains the alkaloid vincamine, which has shown some benefit to people with Alzheimer’s disease.
|
Canker Sores | Refer to label instructions |  [1 star] Periwinkle is an astringent herb that can be used as a mouth rinse to soothe the pain of canker sores. The herb contains tannins that can bind up fluids and possibly relieve inflammation. |
Glaucoma | Refer to label instructions | [1 star] One double-blind and one preliminary study have found that brovincamine, a compound closely related to periwinkle's active constituent vinpocetine, was helpful in people with chronic glaucoma. Until studies have been conducted using actual vinpocetine, it is unknown whether it would be as effective as brovincamine. |
Hearing Loss | Refer to label instructions | [1 star] Periwinke's active constitent vinpocetine has been associated with beneficial effects on hearing loss due to aging (presbyacusis), tinnitus, and ethyl-apovincaminate (a vinca alkaloid) may reduce ringing in the ears (tinnitus). |
Kidney Dialysis | Refer to label instructions | [1 star] One uncontrolled study found that vinpocetine, periwinkle's active constituent, for 3 to 12 months helps eliminate calcium buildup in people undergoing dialysis. |
Menorrhagia | Refer to label instructions | [1 star] Astringent herbs such as periwinkle have been traditionally used for heavy menstruation. |
Tinnitus | Refer to label instructions | [1 star] Periwinkle contains a compound that has been shown to reduce symptoms in people whose tinnitus is due to poor blood flow. |
Vascular Dementia | Refer to label instructions | [1 star] A closely related semisynthetic derivative of vincamine (periwinkle's active constituent) most widely used as medicine is known as ethyl-apovincaminate or vinpocetine. It has been shown in double-blind studies to help alleviate a type of dementia known as vascular dementia, in which the arteries supplying blood to the brain develop atherosclerotic plaques |
Periwinkle has likely been used for medicine for a long time; its Latin name, Vinca, is derived from the Latin word vincere, meaning “to overcome.” European herbalists have used periwinkle for headaches, vertigo, and poor memory since medieval times.1 It was also considered a helpful remedy for conditions with a watery or bloody discharge such as diarrhea, bleeding gums, or menorrhagia.2
