1. Reduce diabetes risk factors
Scientists have already started experimentation to look at the anti-diabetic and hypoglycemic properties of periwinkle leaves. The researchers in Bangladesh of Mymensingh Medical College investigated the effects of Madagascar periwinkle in diabetic rats.
They have found that Madagascar periwinkle had a significant effect on controlling the levels of blood sugar. The study was published in “Mymensingh Medical Journal” in 2007.
The research shows that a strong hypoglycemic (is a condition characterized by an abnormally low level of blood sugar) effects was seen in both diabetic and non-diabetic rats.
The researchers confirmed that the properties of greater periwinkle may be useful in treating diabetes, but more research is needed to test the effects and safety of the plant in humans.
2. Reverse memory loss
The leaves and seeds of the periwinkle contain vincamine, a precursor to the chemical vinpocetine, which is a powerful free radical scavenger. Vinpocetine is used as medicine to enhance memory in aging minds.
Vincamine is as a chemical extract in a supplement form, but the herbalists advise the whole herb to be used in either tea or extract form by using the whole herb one can receive the balanced blend of healing properties that are found naturally in this plant.
Vinpocetine may also help to prevent senility and dementia by preventing damage to the blood vessels in the brain that are caused by free radicals. Vinpocetine thins blood as well as boosts circulation to the brain.
It improves the brain’s ability to absorb nutrients which improve brain function.Periwinkle and vinpocetine are found to be very useful for the treatment for many brain diseases, especially stroke recovery.
It has been used in Europe and Japan as a natural therapy for stroke, as it helps to increase blood flow to areas of the brain with minimal function.
3. Reduce risk of alzheimer’s
Vinpocetine is a chemical derived from vincamine, which is found in the leaves of common periwinkle as well as the seeds of various African plants.
It is used as a treatment for memory loss and mental impairment. It has shown some benefit to people who were associated with Alzheimer’s disease symptoms.
In a preliminary study it was found that vincamine itself has shown to be beneficial in a later double-blind trial. In Europe Vincopetine medicine is sold as in the name of Cavinton and in the US it is also sold as a dietary supplement.
4. Fight against cancer
The periwinkle plant has properties such as vincristine and vinblastine that is believes to be effective in fighting against cancer. The Vincristine and vinblastine bind to tubulin protein in cellular microtubules by preventing polymerization and striking to cellular division by killing the cell.
These properties may also exert immunosuppressant activity which may interfere with other components of the cell cycle to induce cellular death.
The Vincristine and vinblastine are also used for the treatment of leukemia, Hodgkin’s disease, Wilms tumor, neuroblastoma, malignant lymphomas, Kaposi’s sarcoma and mycosis fungoides and many others related diseases.
The researchers and experts have not yet specified the particular doses of periwinkle, but pure alkaloids vincristine and vinblastine are used in cancer therapy as single weekly IV doses of 0.05 to 0.15 mg/kg and 0.1 to 0.2 mg/kg respectively.
