Mawu Oyamba

Levomenthol ndi mankhwala omwe ali ndi dzina la mankhwala (-) -menthol. Lili ndi fungo la mafuta ofunikira ndipo ndi madzi achikasu owala. Chigawo chachikulu cha levomenthol ndi menthol.

 

Levomenthol ali osiyanasiyana zokhudza thupi ndi pharmacological ntchito, kuphatikizapo antibacterial, odana ndi kutupa, analgesic, antipyretic, anthelmintic ndi zotsatira zina.

 

Njira yodziwika bwino yopangira levomenthol ndi kudzera mu distillation ya chomera cha peppermint. Masamba a timbewu ta timbewu timatenthedwa koyamba m'madzi okhazikika, ndipo distillate ikakhazikika, timadzi timene timatulutsa timadzi ta levomenthol. Kenako amasungunulidwa kuti ayeretse, kuyika mtima, ndikupatula menthol.

 

Levomenthol ali ndi chitetezo china, komabe m'pofunika kulabadira zotsatirazi: kupewa yaitali kukhudzana kapena inhalation mkulu woipa wa levomenthol kupewa chifuwa kapena kuyabwa. Malo olowera mpweya wabwino amayenera kusamalidwa pakagwiritsidwe ntchito. Pewani kukhudzana ndi maso ndi khungu ndi kuchepetsa musanagwiritse ntchito.
