  • Calophyllum inophyllum oil has for long been well recognised for its
    theurapeutic properties by local populations around its distribution area.

    Research on Calophyllum inophyllum started in Madagascar in 1951. After a
    slow down, research efforts increased after 1992 when the American Cancer
    Institue discovered that the calanolides, isolated from Calophyllum
    manigerum, where active against strains of HIV-1 in early stage
    reproduction. An other group of tetracycle pyranocoumarins, the inophyllums,
    was isolated from the genus Calophyllum. Both calanolides and inophyllums
    inhibit HIV-1 RT. Numerous plant-derived compounds have been evaluated for
    inhibitory effects on HIV replication in vitro. Anti - HIV coumarins have
    been indentify to inhibit viral absorbtion, reverse transcription, protease
    inhibition and integration in the HIV replication cycle. Clinical trials are
    underway and show that the product tend to be well handeled by patients.

    A patent has been granted to an American company for the Anti HIV
    properties.

    The market potential is of course enormous. Although the tree is easy to
    grow, allready comon, the current local populations use is very limited in
    terms of quantities available, the curent international market for the oils
    is also very limited compared to availability, the seeds are easy to collect
    by local populations, I heard that the industry says the ressource might not
    be enought.

    Planting more trees is not part of the agenda (except for us trying to
    generate more income for the local populations we are working with in order
    for them to be able to preserve the biodiversity of the nearby forest they
    rely on for the moment), funding millions of dollars to synthetise the
    molecule is on the agenda of course.

    This molecule is however a complex one and it might be some time before the
    cure comes out to a large number.

    Ivor, we do fight. I had in mind just a few years ago that individuals could
    make a difference, a few friends had to lent me a few thousands US$, but I
    can see now that my will made that what was a 5000 accre forest meant to
    disapear (with 134 medicinal plants in it) might be preserved while the
    local populations around might see at the same time their standard of living
    improving. My dream is to show people that each of us can do much more for a
    better world. This applies also to private business needing to make some
    profit.

    Large scale goals like fighting against AIDS and wrong drug industry
    development will need joint efforts. I am not a pharmacist but may be trying
    to find out how we could push for research to look into the option of using
    whole plant extract, could be a rewarding fight.

    Standing up on its own can make one feel lonesome, but Ghandi sait "if you
    sand up for a right cause, you'll soon see other people standing up by your
    side", so lets have dreams as he did, and lets achieve at least some of
    them.

    More Than 50 Herbal Medicines Hold Possibility for Cancer Cure

    More Than 50 Herbal Medicines Hold Possibility for Cancer Cure Researches explore the probability of some Chinese herbal medicines to be effective ingredients in making anticancer drugs. (Photo : Getty Images ) Medical experts and nutritionists have long acknowledged that fruits and vegetables contain anticancer properties. Mother Nature seemingly holds another key for cancer prevention and treatment . Chinese scientists learned that 57 kinds of medicinal plants commonly used in creating traditional Chinese medicine have anticancer components, reported Xinhua. Dai Shaoxing from the Chinese Academy of Sciences (CAS) in Beijing, however, said that additional research should be conducted to determine their full potential to cure cancer. The fruit of the medicinal plant Siraitia grosvenorii , for one, contains mogrosides, whose extract--the natural compound mogroside V--was tested for its antitumor effect and its probable capability to treat pancreatic cancer, accor...

    Date palm, bitter kola, zobo top local herbal ‘cures’ for Yuletide blues

    Date palm, bitter kola, zobo top local herbal ‘cures’ for Yuletide blues T 0 Comments Today is Christmas. The Yuletide is here again. The season is synonymous with over indulgence in alcohol, food and sex. Hangover, weight gain and sexually transmitted infections such as Human Immuno-deficiency Virus (HIV) become the order of the day. But scientists have validated bitter kola, date palm, zobo, grapefruit, among others as ‘cures’ for hangover and to prevent weight gain. They advise against unprotected sex and promiscuity, and recommend being faithful to one partner and the use of condom. CHUKWUMA MUANYA writes. THE temptation to drink and get intoxicated with alcohol is high especially during festive periods. The habit, however, comes with the resultant hangover.      Hangover is the experience of various unpleasant physiological and psychological effects following consumption of alcoholic beverages, which can last for more than 24 hours.    ...

    Cytotoxicity of four Aframomum species (A. arundinaceum, A. alboviolaceum, A. kayserianum and A. polyanthum) towards multi-factorial drug resistant cancer cell lines

    Cytotoxicity of four  Aframomum  species ( A. arundinaceum, A. alboviolaceum, A. kayserianum  and  A. polyanthum ) towards multi-factorial drug resistant cancer cell lines Background The search for natural products as potential cytotoxic agents has yielded promising candidates. However multidrug resistance (MDR) is still a major hurdle for patients receiving chemotherapy. In the present study, we evaluated the cytotoxicity of the methanol extracts of four dietary   Aframomum   plant species ( A. arundinaceum, A. alboviolaceum, A. kayserianum   and   A. polyanthum ) against nine sensitive and MDR cancer cell lines. We have also identified the bioactive constituents of   A. arundinaceum . Methods The cytotoxicity of the methanol extracts of the above plants was determined using a resazurin reduction assay. Chromatographic techniques were used to isolate the constituents of   A. arundinaceum. Results A preliminary experiment o...
