Isingeniso

I-Levomenthol iyinhlanganisela ye-organic enegama lamakhemikhali (-)-menthol. Inephunga lamafutha abalulekile futhi iwuketshezi olungenambala ukuya kokuphuzi okukhanyayo. Ingxenye eyinhloko ye-levomenthol i-menthol.

 

I-Levomenthol inezinhlobonhlobo zemisebenzi ye-physiological and pharmacological, kuhlanganise ne-antibacterial, anti-inflammatory, analgesic, antipyretic, anthelmintic neminye imiphumela.

 

Indlela evamile yokwenza i-levomenthol iwukucwiliswa kwesitshalo se-peppermint. Amaqabunga e-mint neziqu ziqala ukushiswa emanzini anganyakazi, futhi lapho i-distillate selehlile, kutholakala i-levomenthol ekhishwe. Ngemuva kwalokho i-distilled ukuze ihlanzwe, igxilise futhi ihlukanise i-menthol.

 

I-Levomenthol inokuphepha okuthile, kodwa kusadingeka ukuthi unake lokhu okulandelayo: gwema ukuchayeka isikhathi eside noma ukuhogela okugxilile kwe-levomenthol ukuvimbela ukungezwani komzimba noma ukucasuka. Indawo enomoya omuhle kufanele igcinwe ngesikhathi sokusetshenziswa. Gwema ukuthintana namehlo nesikhumba futhi uhlambulule ngaphambi kokusetshenziswa.
