What Are Star Ratings?
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.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement,little scientific support.
This supplement has been used in connection with the following health conditions:
| Used for | Why |
|---|---|
| 2 Stars Alzheimer’s Disease Refer to label instructions | Lesser periwinkle contains the alkaloid vincamine, whichhas shown some benefit to people with Alzheimer’s disease. contains the alkaloid vincamine. Supplementation with a semi-synthetic derivative of vincamine, known as vinpocentine, showed no benefit for people with Alzheimer’s disease in a preliminary study, but vincamine itself was shown to be beneficial in a later double-blind trial. |
| 1 Star Canker Sores Refer to label instructions | 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. Historically, herbs known as astringents have been used to soothe the pain of canker sores. These herbs usually contain tannins that can bind up fluids and possibly relieve inflammation. They are used as a mouth rinse and then are spit out. None of these herbs has been studied in modern times. Examples of astringent herbs include agrimony, cranesbill, tormentil, oak, , and witch hazel. Witch hazel is approved by the German Commission E for local inflammations of the mouth, presumably a condition that includes canker sores. |
| 1 Star Diarrhea Refer to label instructions | European herbalists have used periwinkle for conditions with a watery discharge, such as diarrhea. European herbalists have used periwinkle for headaches, vertigo, and poor memory since medieval times. It was also considered a helpful remedy for conditions with a watery or bloody discharge such as diarrhea, bleeding gums, or menorrhagia. |
| 1 Star Glaucoma Refer to label instructions | 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. 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. |
| 1 Star Hearing Loss Refer to label instructions | 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). One double-blind study found that high amounts of vinpocetine (60 mg per day) could have a beneficial effect on hearing loss due to aging (presbyacusis). A preliminary study concluded that supplementation with ethyl-apovincaminate (a vinca alkaloid) may reduce symptoms of tinnitus (ringing in the ears) due to impaired blood flow to the inner ear. One review of the use of vinpocetine in people who have suffered strokes found that the only double-blind study did not show efficacy, though previous uncontrolled studies have suggested there might be a benefit. |
| 1 Star Kidney Dialysis Refer to label instructions | One uncontrolled study found that vinpocetine, periwinkle's active constituent, for 3 to 12 months helps eliminate calcium buildup in people undergoing dialysis. Vinpocetine tends to act as a calcium-chelating agent. One uncontrolled study found that use of vinpocetine for 3 to 12 months could eliminate calcium buildup in people undergoing dialysis. Further research is needed to determine whether this could be helpful in other conditions associated with excess calcium, or whether vinpocetine might interfere with calcium’s beneficial actions. |
| 1 Star Menorrhagia Refer to label instructions | Astringent herbs such as periwinkle have been traditionally used for heavy menstruation. Cinnamon has been used historically for the treatment of various menstrual disorders, including heavy menstruation. This is also the case with shepherd’s purse (Capsella bursa-pastoris). Other herbs known as astringents (tannin-containing plants that tend to decrease discharges), such as cranesbill, , witch hazel, and oak, were traditionally used for heavy menstruation. Human trials are lacking, so the usefulness of these herbs is unknown. Black horehound was sometimes used traditionally for heavy periods, though this approach has not been investigated by modern research. |
| 1 Star Tinnitus Refer to label instructions | Periwinkle contains a compound that has been shown to reduce symptoms in people whose tinnitus is due to poor blood flow. Lesser (Vinca minor) contains a compound known as vincamine. Extracts containing vincamine have been used in Germany to help decrease tinnitus. Preliminary clinical trial data show that vinpocetine, a semi-synthetic version of vincamine, can help reduce symptoms in people whose tinnitus is due to poor blood flow. Because these extracts are not widely available outside of Germany, consult with a doctor knowledgeable in botanical medicine about obtaining them. |
| 1 Star Vascular Dementia Refer to label instructions | 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 A closely related semisynthetic derivative of vincamine most widely used as medicine is known as ethyl-apovincaminate or vinpocetine. It has vasodilating, blood thinning, and memory-enhancing actions. 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. |
Traditional Use (May Not Be Supported by Scientific Studies)
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
How It Works
Botanical names:
Vinca minor
How It Works
There are two classes of active compounds in lesser periwinkle—alkaloids and tannins. The major alkaloid is known as vincamine. A closely related semisynthetic derivative of vincamine most widely used as medicine is known as ethyl-apovincaminate or vinpocetine. It has vasodilating, blood thinning, and memory-enhancing actions. 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.3, 4, 5 A double-blind study found that vincamine can help people with Alzheimer’s disease,6 while one open study did not.7 Vinpocetine has also been found to prevent the decline in short-term memory induced by the anti-anxiety benzodiazepine drug flunitrazepam in one preliminary study.8 Further study is needed to determine whether vinpocetine would be a helpful adjunct to use of benzodiazepines.
One double-blind study found that high amounts of vinpocetine (60 mg per day) could have a beneficial effect on hearing loss due to aging (presbyacusis).9 A preliminary study concluded that supplementation with ethyl-apovincaminate (a vinca alkaloid) may reduce symptoms of tinnitus (ringing in the ears) due to impaired blood flow to the inner ear.10 One review of the use of vinpocetine in people who have suffered strokes found that the only double-blind study did not show efficacy,11 though previous uncontrolled studies have suggested there might be a benefit.12, 13
Vinpocetine tends to act as a calcium-chelating agent. One uncontrolled study found that use of vinpocetine for 3 to 12 months could eliminate calcium buildup in people undergoing dialysis.14 Further research is needed to determine whether this could be helpful in other conditions associated with excess calcium, or whether vinpocetine might interfere with calcium’s beneficial actions.
One double-blind and one preliminary study have found that brovincamine, a compound closely related to vinpocetine, was helpful in people with chronic glaucoma.15, 16 Until studies have been conducted using actual vinpocetine, it is unknown whether it would be as effective as brovincamine.
Crude periwinkle also contains tannins. These make it a mild astringent. It may relieve pain from canker sores or sore throats, according to traditional use. Clinical trials have not been conducted to confirm this.
How to Use It
The amount of vinpocetine used in most studies is 15 mg one to three times per day.17 Vinpocetine should be taken with food, as it has been shown to be better absorbed with meals than when taken away from meals.18 It may take three to six weeks before any improvement is noted.19
A tincture can be taken in the amount of 1 to 2 ml three times per day.20 A tea can be made by infusing 1 teaspoon of herb into a cup of water for 10 to 15 minutes; three cups per day should be drunk.21 Research has not been conducted to determine whether a tincture or a tea provides enough periwinkle compounds to have the same effects as vinpocetine.

Side Effects
Botanical names:
Vinca minor
Side Effects
Vinpocetine has been reported to occasionally cause an upset stomach, flushing of the skin, and a skin rash;22 these effects are mild and rarely cause anyone to stop taking it. The whole periwinkle herb may also cause minor stomach upset. This may be remedied by taking the herb with food. Neither vinpocetine nor periwinkle should be taken during pregnancy or breast-feeding until more information is available. The Commission E of the German government states that some animal studies suggest periwinkle could suppress the immune system.23 This problem has not been observed to date in studies involving vinpocetine.
