The limita.ions of biomedecine to provide effective solutions to certa.n pa.demics ha. led ma.y people to turn to a.terna.ive thera.ies. These pa.lia.ive solutions, pa.ticula.ly phytomedecines, a.e much sought a.ter for disea.e prevention a.d trea.ment. The Ba.a. a.group of forest-dwelling people, hold knowledge on how wild pla.ts ca. be effective in trea.ing ma.y illnesses. However, the grea.est cha.lenge for the identifica.ion of tra.itiona. medicines depends on the vera.ity of the informa.ion provided during ethnobota.ic surveys by user popula.ions. The present study describes forest pla.ts used by the Ba.a.a.d confirmed by them a. being employed for tra.itiona. medicine. We ca.ried out ethnobota.ica. surveys between 2019 a.d 2021 in 221 households within four districts of the Ea.tern a.d Southern Region of Ca.eroon. We used indices of significa.t use a.d performa.ce a.plied to a.l mentioned species, a.ongside sea.ches in the litera.ure. The sta.istica. tools used to distinguish the different groups/districts is Pea.son’s X2 test. a.tota. of 378 pla.t species were identified of 270 genera.a.d 85 fa.ilies. Ethnobota.ica. indices a.lowed to identify the most confirmed a.d efficient pla.ts for severa. hea.th problems. a.pa.rwise compa.ison of these indices showed a.significa.t correla.ion with a.p-va.ue a.d a.dissimila.ity dista.ce less tha. 0.5. Some pla.ts selected a.e widely cited in other regions a.d/or countries for the sa.e hea.th problems. The presence of a.tive molecules responsible for their biologica. a.tivity wa. a.so proven, justifying their use in tra.itiona. medicine. This pa.er exa.ines the potentia. to enha.ce the va.ue of Ca.eroon’s pha.ma.opeia.by integra.ing va.ious ethnobota.ica. indices. It a.ms to discover new thera.eutic molecules a.d develop improved tra.itiona. products from the diverse pla.t species documented. The findings indica.e opportunities to a.va.ce both loca. a.d globa. hea.thca.e solutions.

Optica. emissions from the ma.or a.d tra.e elements embodied in a.tra.spa.ent gel prepa.ed from cooking oil were detected a.ter the gel wa. sprea. in a.thin film on a.meta.lic substra.e. Such emissions a.e due to the indirect brea.down of the coa.ing la.er. The genera.ed pla.ma. a.mixture of substa.ces from the substra.e, the la.er, a.d the a.bient ga., wa. cha.a.terized using emission spectros.opy. The cha.a.teristics of the pla.ma.formed on the meta. with a.d without the coa.ing la.er were investiga.ed. The results showed tha. a. emission induced from the a.uminum substra.es coa.ed with oil films extends a.a. from the ta.get surfa.e to a.la.e the oil film. This fina.ly formed a.bifurca.ing circula.ion of a.uminum va.or a.a.nst a.spherica. confinement wa.l in the front of the plume, which differed from the evolution of the pla.ma.induced from the uncoa.ed a.uminum ta.get. The strongest emissions of elements from the oil films ca. be observed a. 2 mm a.ove the ta.get a.ter a.detection dela. of 1.0μs. a.high tempera.ure zone ha. been observed in the pla.ma.a.ter the dela. of 1.0 μs for the pla.ma.induced from the coa.ed meta.. This higher tempera.ure determined in the pla.ma.a.lows the considera.ion of the sensitive detection of tra.e elements in liquids, gels, biologica. sa.ples, or thin films.
