Icyayi gifite impumuro nziza kirimo ibintu byinshi byuzuye kuruta icyayi kibisi kuko indabyo zatoranijwe zikungahaye kuri glycoside, flavonoide, lactone, coumarine, quercetin, steroid, terpene nibindi bintu bifatika. Muri icyo gihe, icyayi gifite impumuro nziza gikundwa nabaguzi kubera impumuro nziza kandi ikomeye. Nyamara, ugereranije nicyayi kibisi, ubushakashatsi kumikorere yubuzima bwicyayi gifite impumuro nziza ni buke cyane, nicyerekezo cyihutirwa cyubushakashatsi, cyane cyane gukoresha vitro ndetse no muri moderi ya vivo kugirango harebwe isano n’itandukaniro ryimikorere yubuzima bwabahagarariye batandukanye icyayi gifite impumuro nziza nicyayi kibisi, bizagira uruhare runini rwicyayi gifite impumuro nziza. gukoresha no kwiteza imbere. Ubushakashatsi ku mikorere yubuzima bwicyayi gifite impumuro mubindi byerekezo nabyo bifite akamaro kanini, bizafasha kwagura ikoreshwa ryicyayi gifite impumuro nziza. Byongeye kandi, iterambere ryicyayi gihumura gishingiye kumikorere yubuzima gifite akamaro keza, nko gukoresha umutungo nkururabyo rwibinyugunyugu, ururabo rwa loquat, ikibabi cyumurongo, Eucommia eucommia ururabo rwumugabo, nururabo rwa kamelia mugutezimbere icyayi gifite impumuro nziza .
