Devil’s Claw – The People’s Remedy

Devil’s Claw, Harpagophytum procumbens, a medicinal plant native to the Kalahari Desert, has recently become popular in Europe on the alternative medicine market. After being first brought to Germany and studied in laboratories about fifty years ago, the plant is now a recognized drug. It was once gathered by local Bushmen to relieve a variety of symptoms; now it is harvested and exported to Europe on a large scale. The indigenous peoples of Namibia, Botswana and South Africa—the countries where the plant presently grows—have increasingly come to depend on harvesting and selling the plant for their livelihoods. Foreigners, many of them Europeans, have established farms for the commercial production and sale of Devil’s Claw. These developments have been accompanied by serious social, economic and ecological consequences, some beneficial but others dire.
In this study we will investigate the germination potential of Harpagophytum procumbens seeds when exposed to nine different pre-sowing germination treatments including scarification, stratification, imbibition and acidification. Seed viability will also be tested. Root material from Harpagophytum procumbens will be examined for anti-bacterial and anti-oxidant activity by means of laboratory testing with various chemical- and bioassay techniques.
Your findings will contribute to a larger research project currently conducted in Namibia & Botswana in collaboration with Germany. Results from this study will provide the local communities of Namibia with alternative methods to maximize cultivation and promote harvesting of Devil’s Claw!
