Hoʻolauna

ʻO Levomenthol kahi mea hoʻohuihui me ka inoa kemika (-)-menthol. Loaʻa iā ia ke ʻala o nā ʻaila koʻikoʻi a he wai kala ʻole i ka wai melemele māmā. ʻO ka mea nui o ka levomenthol ka menthol.

 

Loaʻa iā Levomenthol nā hana physiological a pharmacological, me ka antibacterial, anti-inflammatory, analgesic, antipyretic, anthelmintic a me nā hopena ʻē aʻe.

 

ʻO ke ala maʻamau no ka hana ʻana i ka levomenthol ma o ka distillation o ka mea kanu peppermint. Hoʻomaʻamaʻa mua ʻia nā lau mint a me nā ʻōpala i loko o ka wai, a i ka wā e maʻalili ai ka distillate, loaʻa kahi extract i loaʻa i ka levomenthol. A laila hoʻomaʻemaʻe ʻia e hoʻomaʻemaʻe, hoʻokaʻawale a hoʻokaʻawale i ka menthol.

 

Loaʻa i ka Levomenthol kahi palekana, akā pono nō e hoʻolohe i kēia mau mea: pale i ka hoʻolaha lōʻihi a i ʻole ka inhalation o nā kiʻekiʻe kiʻekiʻe o ka levomenthol e pale ai i nā allergies a i ʻole ka huhū. Pono e mālama ʻia kahi kaiapuni maikaʻi i ka wā e hoʻohana ai. Hōʻalo i ka pili ʻana me nā maka a me ka ʻili a dilute ma mua o ka hoʻohana ʻana.
