Ingabe kuphephile ukusebenzisa imikhiqizo yamalahle welahle?
Imikhiqizo yamalahle yamalahle we- psoriasis iye yazungeze iminyaka engaphezu kwekhulu. I-tar yamalahle yilezi zinto ezishiywe yi-coal processing processing and distillation. Kukhona izinkulungwane zamakhemikhali ematheni wamalahle, futhi ingxenye eyodwa kuphela yalezi zikhonjisiwe.

Kunoma yikuphi, i-tar yamalahle igcwele, njengoba sekube yimithi isikhathi eside kunokuba i-FDA ikhona. Ngaphambi kokuba i- corticosteroids ihlonzwe kuqala noma isetshenziselwe ukusetshenziswa kwezifo zesikhumba esivuthayo, kwakungenhla yamakhaza ukusiza ukunciphisa itchki. Amalungiselelo okugaya amalahle abonakala enza izinzuzo zabo zokulwa ne-psoriasis ngokuphazamisa i-DNA futhi ngaleyo ndlela anciphisa ukukhula kwegciwane lesikhumba kanye nenzuzo. Umphumela wesikhathi eside wukunciphisa ama-plaque we-psoriatic.
I-Coal Tar Isetshenziswa Kanjani?
I-tar yamalahle itholakala ezinqwabeni ze-over-the-counter (OTC) psoriasis nama shampoos amancane, kanye nama-creams, ama-gel, nezithasiselo zokugeza.

Ingabe Amalahle Ayingqayizivele?
With izithako eziningi ezingaziwa, lo mbuzo awulula kakhulu ukuphendula ngokucacile.
Nokho, amaphesenti angama-5 noma amalahle amakhulu amakhulu ahlukaniswa njenge-carcinogen (i-agent edala umdlavuza) yi-World Health Organization's International Agency for Research on Cancer. Kule ndaba, isigaba esifanayo ne-methoxsalen (esetshenziselwa ukwelashwa kwe-PUVA ye-psoriasis) nemisebe yelanga, ezinye izinhlobo ezimbili zokwelapha i-psoriasis. Iziphuzo ezidakayo kanye nogwayi nazo zifanelekile kulesi sigaba.

I-FDA, ngokuphambene, ibheka amaphesenti ama-0.5 kuya ku-5 amaphesenti amalahle we-OTC aphephile i-psoriasis, futhi abukho ubufakazi obuqhathanisa nalezi zilungiso ezibuthakathaka ekwandeni ingozi yomdlavuza. Nakuba ama-tar amakhemikhali elahlekile atholakale emcinini wabasebenzisi be-shampoo esekelwe ekutheni, ukugxilongwa kwe-tar yamalahle okusetshenzisiwe kwakungaphezu kwezikhathi ezingu-100 kunalezo ze-shampoo ezivamile ze-OTC.
Ucwaningo luye lwacutshungulwa ukuze kubone ukuthi ingabe amalahle alahlekelwa ingozi yomdlavuza. Ucwaningo olulodwa alutholanga ingozi enkulu yomdlavuza wesibeletho uma isetshenziselwa izifo zesikhumba.
Esinye isifundo esikhulu ngabantu abane-psoriasis ne-eczema akutholakali ingozi enkulu yomdlavuza wesikhumba noma izidakamizwa ezingekho isikhumba.
