Kava ikomoka ku kawa, izwi kandi ku izina rya kava ibyatsi, ni ibimera biva mu karere ka pasifika yepfo bifite umutuzo, kuruhuka no kurwanya amaganya. Ibimera bya Kava bikura mu bihugu byinshi birwa muri Oseyaniya, nka Fiji, Vanuatu na Samoa, kandi bikoreshwa n’abaturage baho nkumuti gakondo w’ibimera kugira ngo ugabanye amaganya, utera ibitotsi kandi woroshye umubiri nubwenge.

Ikintu cyingenzi kigizwe na kava ni kavalone, imiti igabanya ubukana ifata ubwonko bwa neurotransmitter mu bwonko, ikabyara ingaruka nziza kandi zishimishije. Kubera iyo mpamvu, ikivamo cya kava gikoreshwa cyane mubuvuzi bwimiti gakondo nubuvuzi gakondo kugirango bivure amaganya, kudasinzira, no guhagarika umutima.

Mu myaka yashize, uko ubushake bwo kuvura imiti n’ibimera bwiyongereye, ikivamo kava cyitabiriwe n’isi yose. Ubushakashatsi bwinshi bwerekanye ko ikivamo cya kava gifite ingaruka zimwe na zimwe zo kurwanya no guhangayika, kandi ugereranije n’imiti gakondo itera imiti, igira ingaruka nke kandi ikagira ingaruka nke ku mubiri.

Ariko, ni ngombwa kumenya ko ikuramo rya kava ridakwiriye abantu bose. Gukoresha igihe kirekire cyangwa birenze urugero bya kava bishobora gutera umwijima, bityo abantu barwaye umwijima cyangwa gufata indi miti bagomba kuyikoresha babyitondeye. Byongeye kandi, abagore batwite n'abonsa bagomba kwirinda gukuramo kava.

Muri rusange, ikivamo cya kava, nkumuti gakondo wibimera, gifite ingaruka zimwe na zimwe zo gutuza no kurwanya amaganya, ariko bigomba gukoreshwa ubwitonzi, kandi nibyiza ko ubikoresha uyobowe na muganga kugirango umutekano urusheho kugenda neza. Mugihe ubushakashatsi mubuvuzi karemano bukomeje kwiyongera, byizerwa ko ikivamo kava kizagira amahirwe menshi yo gukoreshwa mugihe kizaza.
