Intshayelelo

I-Levomenthol yi-organic compound enegama lekhemikhali (-)-menthol. Inevumba elimnandi le-oyile kwaye ilulwelo olungenambala ukuya kumthubi. Inxalenye ephambili ye-levomenthol yi-menthol.

 

I-Levomenthol inoluhlu lwemisebenzi ye-physiological and pharmacological, kubandakanywa ne-antibacterial, anti-inflammatory, analgesic, antipyretic, anthelmintic kunye nezinye iziphumo.

 

Indlela eqhelekileyo yokwenza i-levomenthol kukusebenzisa i-distillation yesityalo se-peppermint. Amagqabi e-mint kunye neziqu zifudumeza kuqala emanzini, kwaye xa i-distillate ipholile, isicatshulwa esine-levomenthol sifumaneka. Emva koko i-distilled ukuze ihlambuluke, igxininise, kwaye ihlukanise i-menthol.

 

I-Levomenthol inokhuseleko oluthile, kodwa kusekho imfuneko yokunikela ingqalelo koku kulandelayo: kuphephe ukuvezwa ixesha elide okanye ukuphefumla iqondo eliphezulu le-levomenthol ukuthintela ukwaliwa okanye ukucaphuka. Indawo engenawo umoya kufuneka igcinwe ngexesha lokusetyenziswa. Kuphephe ukudibana namehlo kunye nolusu kwaye uhlambulule ngaphambi kokusetyenziswa.
