I-Kava, eyaziwa nangokuthi i- Piper methysticum , i-shrub ende ende kwintsapho ye-pepper ekhula kwiziqithi zaseMzantsi Pacific. Isetyenziselwe khona iminyaka eyiwaka leminyaka njengendlela yokulungisa isicatshulwa kunye nesiphuzo sentlalo kunye nesidlo.
Inxalenye yesityalo esetyenziswe imithi yinkcazo. Nangona ingcambu yayisetyenziswe okanye yenziwe isiphuzo, i-kava ikhona ngokukhoyo kwi-capsule, tablet, isiphuzo, itiye, kunye neefom ze-extract.
Izixhobo eziphambili kwiingcambu ze-kava zibizwa ngokuba ngama-kavalactones. Iintlobo ezithile ze-kavalactones ziquka i-dihydrokavain, i-methysticin, i-kavain, i-dihydromethysticin, i-dihydrokawain, i-yangonin kunye ne-desmethoxyyangonin.
Ukusetyenziswa kweKava
- Ukuxhalabisa
- Ukungabikho
Ngenxa yokuba i-kava inokubangela i-sedation, kwaye ixabiso eliphezulu, ukuxiliswa, ukusela izidakamizwa zidliwe kwezinye iindawo zehlabathi ngendlela efanayo notywala.
Izinzuzo zeKava
Ngoku kukho ukungabikho kokuhlolwa kweekliniki kwimiphumo ye-kava. Ngo-2003, ukuhlaziywa koBambiswano beCchrane kuhlolisise uphando olukhoyo ukuze lubone indlela ehamba ngayo xa kuthelekiswa ne-placebo ekuphatheni ixhala. Emva kokuhlalutya izifundo ezili-11 (ezibandakanya abantu abangama-645) abaye bahlangabezana neendlela, abaphandi baphetha ngokuthi i-kava "ibonakala iyindlela efanelekileyo yokwenza unyango." Nangona kunjalo, bongezelela ukuba kubonakala ngathi yincinci.
Ukukhathazeka Nge-Kava kunye neNtsholongwane
Iingxelo zenkcazo ziye zadibanisa i-kava kunye nesifo sobungozi, kubandakanya i-hepatitis, i-cirrhosis, ukuhluleka kwesibindi, kunye nokufa.
Ngenxa yoko, i-FDA ikhuphe izilumkiso malunga nevava. Amazwe amaninzi avimbele okanye avimbela ukuthengiswa kwe-kava.
Iziphumo ezintle zesibindi zibonakala zidibene neziganeko ezifana nezifo zesibindi zangaphambili ezikhoyo, ukusetyenziswa kotywala, ukulingana ngokweqile, ukuhluka kofuzo kwi-enzyme ye-cytochrome P450, ukusetyenziswa kwamanye amayeza okanye imifuno edibeneyo, inokuchaphazeleka, okanye ukusetyenziswa iziqu okanye amaqabunga amaqabunga okanye amacwecwe ayenziwe nge-acetone okanye i-ethanol.
Ezinye iiplanga
Iziphumo ezinokubakho ziquka ukuhlengahlengwa, umlomo omqubuzelayo, ukugqithwa kwesikhumba, intloko, ukulala nokuphazamiseka okubonakalayo. Ukusetyenziswa okungapheliyo okanye okunzima kwe-kava kuye kwaxhomekeka kwi-pulmonary hypertension, ukukhutshwa kwesikhumba, ukulahleka kwemisipha, ukulimala kweengtso kunye nokungaqhelekanga kwegazi.
I-Kava inokunciphisa uxinzelelo lwegazi kwaye inokuphazamisa i-clotting yegazi, ngoko akufanele isetyenziswe ngabantu abaneengxaki zokuphuma kwegazi.
Abantu abanesifo sika-Parkinson akufanele basebenzise i-kava kuba kungangonakalisa iimpawu.
I-Kava akufanele ithatyathwe ngabantu abathwala imithi ye-Parkinson yezifo, izidakamizwa ze-antipsychotic, okanye nayiphina imithi echaphazela amazinga e-dopamine.
I-Kava akufanele idibaniswe notywala okanye imithi yokuxhalaba okanye ukulala, kubandakanya i-benzodiazepines efana neValium (diazepam) okanye i-Ativan (lorazepam). Ingaba nefuthe elongezelelweyo xa kuthathwa ngamachiza obangela ukulala.
I-Kava inokuba nempembelelo yokongeza xa idibene neziyobisi ezixinzelelekileyo zibizwa ngokuba yi-monoamine oxidase inhibitors (MAOI).
I-Kava akufanele ithatyathwe naliphi na iziyobisi okanye imifuno echaphazela ukusebenza kwesibindi. I-Kava nayo inokuphazamisa i-blood clotting, ngoko abantu abathatha i-Coumadin (i-warfarin) okanye nasiphi na isicatshulwa esichaphazela i-clotting yegazi kufuneka sikuphephe ngaphandle kokuba phantsi kweliso lugqirha.
I-Kava i-diuretic, ngoko inokuba nempembelelo eyongeziweyo xa idibene neziyobisi okanye izityalo ezinezakhiwo ze-diuretic.
I-Kava akufanele ithathwe phakathi kweveki ezimbini zokuhlinzwa.
I-supplement ka-Kava ayizange ihlolwe ukhuseleko kwaye igcine ingqalelo ukuba ukhuseleko lwezongezelelo kwabasetyhini abakhulelweyo, oomama abancinci, abantwana kunye nalabo abanezifo zonyango okanye abathabatha imishanguzo ayilwanga. Unokufumana iingcebiso ekusebenziseni izongezo apha kodwa ukuba ucinga nge-kava, ncokola nomboneleli wakho oyintloko.
