Lesi sithelo siyimbulunga (uma simile endle) noma simise okweqanda (uma sitshaliwe) futhi siluhlaza okotshani obuphaphathekile sisho ngemithende eluhlaza njengotshani obuzothile. Imbewu ikhiqiza amafutha anothile aphuzi, asetshenziswa kwezokugcoba zobuhle, akhulisa nezinwele ngesithako salo esisensisheni kanti imbewu yalo agayiwe iyasetshenziswa ukuhhudla isikhumba isisuse insila.
Amafutha ebhece laseKalahari anezinga le-omega-6 essential fatty acid (68%) elithi alifane nele-evening primrose (72%), linezithako eziqeda ukulunywa, libuyisela ukunwebeka kwesikhumba futhi lilwisana nokushwabana. Angamafutha amahle omntwana futhi angaxutshwa nemanye amafutha. La mafutha akhishwa embewini egayiwe emva kokomisa kwayo. Lesi simila esinaba phansi esisho ngezimbali eziphuzi sikhula kahle endaweni enonhlaba oyisihlabathi, onemvundo encane. Linamandla, liyamelana nesomiso futhi lingabayigugu njengesithombo esitshalwa phakathi kwezinye ukuze sibambe inhlabathi ukuthi ingaguguleki ivimbe nokuphela kwamanzi.
