Oyagbemi AA, Saba AB, Azeez OI. Capsaicin: a novel chemopreventive molecule and its underlying molecular mechanisms of action. Indian J Cancer. 2010 Jan-Mar;47(1):53-8 [open access]
Researchers at the University of Ibadan undertook a review of the literature on the plant genus Capsicum (Solanaceae), a principal ingredient of hot red and chili peppers, as a cancer-suppressing agent.
From the conclusion:
“The use of phytochemicals present in fruits and vegetable has gained worldwide acceptance as a novel source of chemopreventive agents against cancer cells. These non-nutrient phytochemicals either block or reverse multistage carcinogenesis. Capsaicin, a pungent ingredient present in chili pepper has anti-inflammatory, antioxidant, antiproliferative and anti-cancer potentials. Capsaicin has chemopreventive effect against a wide of chronic inflammatory diseases, including cancer. Other potential benefits of capsaicin should be explored with the aim of brightening our understanding of the molecular mechanism associated with its anti-cancer activities.”

Mesfin F, Demissew S, Teklehaymanot T. An ethnobotanical study of medicinal plants in Wonago Woreda, SNNPR, Ethiopia. J Ethnobiol Ethnomed. 2009 Oct 12;5:28 [open access]
Researchers at Addis Ababa University documented medicinal plants in the natural vegetation and home gardens in Wonago Woreda, Ethiopia. They collected 155 plant species from the natural vegetation and 65 species from home gardens, and documented 72 as having medicinal value for human or livestock ailments.
Healers have turned to home gardens in the face of threat to natural vegetation:
“Traditional medicinal plants were harvested mostly from natural vegetation area followed by home gardens. They were also obtained from roadsides, farmlands and live fences. The medicinal plants in the natural vegetation were under threat and to tackle these problems traditional healers had turned their face towards home gardens. However, traditional healers still depend largely on naturally growing species because of their belief that those species in the natural vegetation are more effective in the prevention and treatment of diseases and health problems.”
This article is particularly valuable because of the detailed attention to preparation and application of the medicinal plants for specific ailments.
Pieroni A, Giusti ME. Alpine ethnobotany in Italy: traditional knowledge of gastronomic and medicinal plants among the Occitans of the upper Varaita valley, Piedmont. J Ethnobiol Ethnomed. 2009 Nov 6;5:32. [open access]
Researchers at the University of Gastronomic Sciences and Università degli Studi di Firenze undertook a gastronomic and medical ethnobotanical study among the Occitan communities living in Blins/Bellino and Chianale, in the upper Val Varaita, in the Piedmontese Alps of Northwestern Italy. Traditional uses of 88 plants were recorded.
Sustainability is a serious concern:
It is … evident that traditional knowledge in the Varaita valley has been heavily eroded. This study also examined the local legal framework for the gathering of botanical taxa, and the potential utilization of the most quoted medicinal and food wild herbs in the local market, and suggests that the continuing widespread local collection from the wild of the aerial parts of Alpine wormwood for preparing liqueurs (Artemisia genipi, A. glacialis, and A. umbelliformis) should be seriously reconsidered in terms of sustainability, given the limited availability of these species, even though their collection is culturally salient in the entire study area.

Giday M, Asfaw Z, Woldu Z, Teklehaymanot T. Medicinal plant knowledge of the Bench ethnic group of Ethiopia: an ethnobotanical investigation. J Ethnobiol Ethnomed. 2009 Nov 13;5:34 [open access]
Researchers at Addis Ababa University documented and analyzed medicinal plant knowledge of the Bench ethnic group in Ethiopia. Malaria, respiratory tract infections, intestinal parasites, skin-related diseases and typhoid fever are the major human health problems among the people. The study revealed 35 medicinal plant species used by the Bench.
From the conclusion:
“The immediate and serious threat to the local medical practice in the study area seems to have come from the increasing influence of modernization. As there is no adequate modern healthcare service provision in the study area, loss of local medical knowledge and practice could negatively affect the healthcare system of the people. To arrest or slow down the trend, awareness on the contribution of traditional medical practice towards fulfilling the primary healthcare needs of the local people should be created among the youth.”
An old story. Past time to start listening.
