Gurba (pishak) — in jonvar navhoi khonagi, vahshi va obi dorad. Mizoji gurbai khonagi dar darajai duvum garm va rutubatash bisyor, yane tar ast. Hislathoi shifobakhshi on: khurdani gushti gurbai khonagi ba piron va tarmizojon muvofiq ast: dardi bugumhoro, ki az tari boshad, bemorii niqris va dabbaro, ki az daridani pardai shikam boshad, doru meshavad, gurdaro garm megardonad, bavosir va dardi pushtro sudmand ast.
Agar az pustash pustin dukhta bipushand, badanro garm mekunad, khususan pusti gurbai obi, ki pashmash mahintar va daroztar ast, inchunin pusti gurbai pashmdarozi digar ba on nazdik ast. Gurbaro dar kuza jo karda, dar tanuri tafson yo dar kurai hammom bisuzand, to on ki khokistar gardad, onro bo sirko sirishta, bo pari murg bimoland, kafidani angushtoni dastu pohoro shifo mebakhshad.
Mizoji sarginash dar garmi qavi ast. Agar onro zanho az tag bardorand yo sukhta ba dudash khudro bidorand, hamrohaki (yoraki) bacharo az shikami onho meaftonad. Gushti navi gurbaro guzoshta bandand, niqrisro daf mekunad. Gushti khushkashro kufta, guzoshta bandand, tir va khori daromadaro az badan berun mekashad, ustukhoni shikastaro ba ham mepayvandad.
Bo gurba hamnafas shudan va khurdani gushti on logar mekunad va illati silro ba ham merasonad. Tabib Mahryorus guftaast, ki magzi sari onro bo obi indovi ziroati biyoshomand, chakmezak va dardi gurdaro davo meshavad.
Zahrai gurbai siyohro bo ravgani savsani safed yo ravgani savsani kuhi daromekhta, dar bini birezand, kaj shudani ruyro shifo mebakhshad, muyro siyoh mekunad. Agar in zahrai onro dar vaqti zoidan ba chashm kashand, dar shab tezbin megardand. 1,75 gramm zahrai onro bo ravgani zaytun daromekhta dar bini rezand, kaj shudani ruyro shifo mebakhshad, agar bo namaki kufta daromekhta bimoland, jarohati kuhnaro ba ibro meovarad.
Sipurzi gurbai siyohro zanhoe, ki hayzashon bemavridu bamavrid ravon meshavad, ba ronashon biyovezand, khuni ravoni onhoro man mekunad. Hakim Arastu meguyad, ki khoyai khushki gurbaro kufta, dar bini birezand, baroi illati makhav bagoyat foidabakhsh ast.
Gurbai vahshi dar namud shisharang ast, az khonagi kalontar meboshad, muyash kamtar. Baroi davoi qavitar az khonagi buvad. Mizojash dar darajai duvum garm va khushk ast.

Hurdani gushti in joiz nest, zero ki binobar murdorkhur budanash dar badan murdori meovarad. Agar gurbai vahshi kasro bigazad, dardi bisyor va sabzii rangi badan meovarad. Davoi in pudinai dashti yo piyozro kufta, ba joyi gazidaash guzoshta bastan ast.
