Cholinga chachikulu
Mankhwala a biochemical omwe ali ndi phindu lalikulu lachipatala amagwiritsidwa ntchito kwambiri popanga maopaleshoni osiyanasiyana a maso, monga kuyika ma lens, kupatsira ma cornea ndi opaleshoni ya antiglaucoma.Itha kugwiritsidwanso ntchito pochiza nyamakazi ndikufulumizitsa machiritso a bala.Akagwiritsidwa ntchito mu zodzoladzola, amatha kukhala ndi gawo lapadera poteteza khungu, kusunga khungu lonyowa, losalala, lofewa, lachifundo komanso lotanuka, ndipo limakhala ndi ntchito zotsutsana ndi makwinya, anti-khwinya, kukongola ndi chisamaliro chaumoyo, ndikubwezeretsanso ntchito za thupi.
