Anti-cancer: Rosy periwinkle

This pretty plant from Madagascar gives us two very important cancer-fighting medicines: vinblastine and vincristine. Vinblastine has helped increase the chance of surviving childhood leukaemia from 10% to 95%, while vincristine is used to treat Hodgkins’ Disease.

Traditional Madagascan healers used the rosy periwinkle for treating diabetes. This led to its study by western scientists who then discovered its anti-cancer properties.

Profit sharing

These medicines have proved very profitable for global drug companies. Worldwide sales are worth over £75 million a year, but virtually none of this money finds its way back to Madagascar, one of the poorest countries in the world.

Some pharmaceutical companies are trying to redress this imbalance by working closely with ethno-botanists and indigenous healers, and sharing profits more equitably.

There are also recent international agreements which have tried to ensure that more profits from the commercial development of animal and plant species return to the countries of origin.

One such agreement is the Convention on Biological Diversity which seeks the ‘fair and equitable sharing of the benefits from the use of genetic resources’, together with the conservation of biological diversity and the sustainable use of its components

    You can find this plant during spring and summer in a range of colors from white to dark pink in US nurseries where it is sold by the name of Vinca. For cancer treatment the Vinca plant with white flowers is used in Puerto Rico, where a tea is made using its flowers. There, they only use the white flowers that have the yellow center and not the white flowers with the pink center. They start making the tea with one flower boiling it in 7 oz. of water for no longer than a minute. They drink this tea on an empty stomach once a day. Then they add another flower each day until they reach five flowers on the fifth day. They continue taking the five flowers’ tea until their illness is resolved. It takes between 4 to 5 months for the tumor(s) to disappear. The nice thing is that meantime this tea keeps metastases from taking place. You can also find a Periwinkle extract on the web. 20 to 30 drops of this extract are taken in a glass of water once a day. Both are very effective.

    This important medicinal plant has been given many names creating some confusion. Madagascar periwinkle, ‘sadaphuli’, Catharantus roseus, Vinca rocea or Vinca as it’s known in the United States is used as an alternative treatment for many forms of cancer. This comes as no surprise because Vinca’s cancer killing properties have been recognized by the pharmaceutical industry resulting in the isolation of several Vinca compounds that are currently used by medicine in chemotherapy treatments for childhood leukemia, Hodgkin’s disease, testicular cancer and cancerous tumors. Vinca is a treasure chest plant that containins more than 400 known alkaloids!

    If this is not impressive enough, Vinca taken as a daily supplement is known to improve blood supply to the brain, increase oxygen and glucose for the brain to use, prevent abnormal coagulation of blood, and raise brain levels of the neurotransmitter serotonin.

    There are two classes of active compounds in Vinca: alkaloids and tannins. One important alkaloid is vincamine. A closely related semi-synthetic derivative of vincamine widely used in medicine is known as ethyl-apovincaminate or vinpocetine. It has vasodilating, blood thinning, and memory-enhancing actions 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.

    Extracts of Vinca have significant anticancer activity against numerous cell types. The greatest activity is seen against multi-drug resistant tumor types which suggest that there are compounds in Vinca rosea that are synergistic or additive with anti-neoplastic elements which help inhibit resistance to these drugs.

    Some people may experience side effects associated with the prolonged use of Vinca flower tea or Periwinkle extract such as hair loss and bouts of urticaria.

  23. Frank says:

    Cape Town, South Africa…Nat Geog film last week showed this plant, I recognised it in my garden as ground cover ornamental plant with pink flowers. and google brought me to your site. Seems tough, grows in our Mediterranean type climate without summer watering, in very sandy porous soil (like Florida). Flowers all year round, selfseeding. No one here knows of its med properties. Interested in more scientific, medical references for its dosageuse for curative and preventive purposes.

  24. Frank says:

    Apparently one should be careful of self-dosing treatment of this plant, according to some medical references. It can be potentially toxic according to This site reports the general value of the extracts under doctor treatment, but says there is no recent clinical evidence to support specific doses of the periwinkle herb (plant source). It advises pregnant and breast-feeding women to avoid it. It says it can cause acute dyspnea and other reactions. This medical reference should be read by people wanting to self-dose. Of course, drug companies may have a vested interest in advising against self-dosing, the question then arises – if you self-dose, what is the right dosage, how often, and should you chew and spit our, or boil and drink. I would like to use it,but now I’m a bit worried.
    Any further comments on how to use the plant itself?

  25. Sheetal says:

    This plant grows on roads in India. There are lots of these flowers available in dry powder form. Boil around 10 flowers with 1 tsp cumin seeds and drink the strained water every morning. You can see that the diabetes goes down in a month. Worked for my dad… You get around 15 new flowers each day…
