Inhlanganisela equkethwe emaqabungeni nasemagxolweni esihlahla se-Voacanga africana ivikela amangqamuzana ezinguqukweni eziholela ekwakhekeni kwezifo ze-Alzheimer's, Parkinson kanye ne-nurodegenerative ebuchosheni, kubika i-Journal of Ethnopharmacology.
Abantu baseSão Tomé nasePríncipe eGulf of Guinea baye basebenzisa amaqabunga namagxolo alesi sihlahla amakhulu eminyaka ukuze belaphe ukuvuvukala nokunciphisa ukugula kwengqondo.
Ososayensi abavela ku-Salk Institute for Biological Studies e-US bahlaziye izingcaphuno ezivela ezinhlobonhlobo zezitshalo ezinhlanu ezitholakala eziqhingini. Ezintathu zazo zazisetshenziswa izinyanga zendawo. Umthelela wokukhishwa uhlolwe kumaseli omuntu namagundane. Kwavela ukuthi isihlahla se-Vocanga africana sikhipha amangqamuzana avikelwe ekucindezelekeni kwe-oxidative, okungabangela ukulimala kwe-DNA futhi kuholele ku-neurodegeneration. Ngaphezu kwalokho, yayinemiphumela yokulwa nokuvuvukala futhi yavimbela ukwakheka kwe-amyloid-beta ekhuthaza ukuthuthukiswa kwesifo i-Alzheimer's.
Kuyisithako esingaba khona emithini emisha. Miningi imithombo enjalo yezinhlanganisela ezizuzisayo nezinamandla ezitholakala ezindaweni ezihlukahlukene emhlabeni jikelele. Iningi labo alikaze lihlolwe - kugcizelela umbhali wocwaningo, uPamela Maher. (PAP)
