“…We suggest, however, that future studies should focus on the potential of popular bitter African vegetables (e.g., Gnetum africanum Welw., Solanum spp., Momordia charantia L., and Vernonia amygdalina Delile) for diabetes prevention among migrants, as some of these have proven anti-diabetic effects (Atangwho et al 2014; Van Andel and Carvalheiro 2013). The same accounts for vegetables consumed to lower hypertension, such as the two species mentioned by our informants (onions and Hibiscus sabdariffa ), which both show activity against high blood pressure (Gbolade 2012; Walton et al 2016). Although not relevant for the Belgian health situation, plant uses to combat tropical diseases such as malaria and intestinal parasites were still mentioned during our interviews, probably because they remain relevant for migrants frequently visiting their homeland.…”

(English)Maintaining cultural identity and preference to treat cultural bound ailments with herbal medicine are motivations for migrants to continue using medicinal plants from their home country after moving to Europe and the USA. As it is generally easier to import exotic food than herbal medicine, migrants often shift to using species that double as food and medicine. This paper focuses on the trade in African medicinal plants in a Congolese neighborhood in Brussels (Belgium). What African medicinal plants are sold in Matonge, where do they come from, and to which extent are they food medicines? Does vendor ethnicity influence the diversity of the herbal medicine sold? We hypothesized that most medicinal plants, traders, and clients in Matonge were of Congolese origin, most plants used medicinally were mainly food crops and that culture-bound illnesses played a prominent role in medicinal plant use. We carried out a market survey in 2014 that involved an inventory of medicinal plants in 19 shops and interviews with 10 clients of African descent, voucher collection and data gathering on vernacular names and uses. We encountered 83 medicinal plant species, of which 71% was primarily used for food. The shredded leaves of Gnetum africanum Welw., Manihot esculenta Crantz, and Ipomoea batatas (L.) Lam were among the most frequently sold vegetables with medicinal uses. Cola nuts, shea butter, Aloe vera (L.) Burm.f., and Mondia whitei (Hook.f.). Skeels were the main non-food medicines sold. Women’s health, aphrodisiacs, and rituals were the most important medicinal applications, but culture-bound ailments did not entirely dominate the plant uses. While most clients in Matonge were Congolese, most vendors and plant species were not. The Pakistanis dominated the food trade, and typical Congolese plants were sometimes replaced by West African species, creating confusion in vernacular names. African-managed shops had significantly more species of medicinal plants in stock than shops managed by Pakistanis. Almost all non-food herbal medicine was sold by Africans. Apart from informal shops, non-food herbal medicine was also sold from private homes and by ambulant vendors, probably to reduce costs and escape taxes and control by the authorities. We expect that in the future, increasing rent, strict regulations, and decreasing investments by the Congolese community will force the medicinal plant trade in Matonge to go even more underground.Electronic supplementary materialThe online version of this article (doi:10.1007/s12231-016-9365-8) contains supplementary material, which is available to authorized users.

“…The rates of THM use among adults with HTN in SSA were higher than those reported in 2 recent studies from the UK [24] and India [23] that found a prevalence of 28.8% and 14.4% respectively. Several studies explore the types of THM used to treat hypertensive patients [28–30], but very few quantify the amount of THM use. The high prevalence of THM use among adults with HTN in all 4 of these studies highlights the importance of considering the possible effects of THM use on HTN treatment and control in SSA.…”

Traditional Herbal Medicine Use Among Hypertensive Patients in Sub-Saharan Africa: A Systematic Review

et al. 2014

View full text Add to dashboard Cite

Background Hypertension is increasingly common in sub-Saharan Africa, and rates of hypertension control are low. Use of traditional herbal medicines (THM) is common among adults in sub-Saharan Africa and may affect hypertension therapy. Methods We searched Ovid MEDLINE, Ovid EMBASE, and Web of Knowledge in June 2013 to find studies about THM use among hypertensive patients living in sub-Saharan Africa. Two independent reviewers evaluated titles and abstracts. Qualifying references were reviewed in full text. Data were extracted using a standardized questionnaire. Results Four hundred eighty-one references were retrieved, and 4 articles from 2 countries met criteria for inclusion. The prevalence of THM use was 25-65% (average 38.6%). THM was the most common type of complementary and alternative medicines used by patients (86.7%-96.6%). Among THM users, 47.5% concomitantly used both allopathic medicine and THM. Increased age (p<0.001), male sex (RR 2.58), belief in a supernatural cause of hypertension (RR 2.11), and family history of hypertension (OR 1.78) were positively associated with THM use while belief that hypertension is preventable was negatively associated with THM use (OR 0.57). Conclusion More than a third of adults with hypertension in sub-Saharan Africa use THM. Half of these patients use THM concurrently with allopathic medicine. Healthcare workers in sub-Saharan Africa must discuss THM use with their hypertensive patients. More research is urgently needed to define the impact of THM use on hypertension control and outcomes in sub-Saharan Africa.

Plants Producing Ribosome-Inactivating Proteins in Traditional Medicine

et al. 2016

View full text Add to dashboard Cite

Ribosome-inactivating proteins (RIPs) are enzymes that deadenylate nucleic acids and are broadly distributed in the plant kingdom. Many plants that contain RIPs are listed in the pharmacopoeias of folk medicine all over the world, mostly because of their toxicity. This review analyses the position occupied in traditional medicine by plants from which RIPs have been isolated. The overview starts from the antique age of the Mediterranean area with ancient Egypt, followed by the Greek and Roman classic period. Then, the ancient oriental civilizations of China and India are evaluated. More recently, Unani medicine and European folk medicine are examined. Finally, the African and American folk medicines are taken into consideration. In conclusion, a list of RIP-expressing plants, which have been used in folk medicine, is provided with the geographical distribution and the prescriptions that are recommended by traditional healers. Some final considerations are provided on the present utilization of such herbal treatments, both in developing and developed countries, often in the absence of scientific validation. The most promising prospect for the medicinal use of RIP-expressing plants is the conjugation of purified RIPs to antibodies that recognise tumour antigens for cancer therapy.
