Sarson ke tel ki maalish (sardi ki rookhi twacha)

Parampara kya kehti hai

Uttar Bharat, Bihar aur Bengal me sardi aate hi sarson ke tel ki maalish shuru ho jati hai. Kaha jata hai ki yeh sharir me garmi bharta hai, haddi mazboot karta hai, twacha ko phatne nahi deta aur bachche ki neend achhi karta hai. Nani-dadi ke liye yeh navjaat ki dekhbhal ka hissa hai. Yeh sab daave parampara ke hain - aur inhi me se kuch ko research ne jaancha bhi hai.

Across north India, Bihar and Bengal, winter starts and the mustard oil comes out. The claims are that it fills the body with heat, strengthens bones, stops skin from cracking and helps a baby sleep. For many older women in the family it is simply part of newborn care. These are traditional claims - and unusually, some of them have actually been examined.

Shodh kya kehti hai

Sabut milta-julta hai

Yahan research hui hai, par usse baat kisi bhi taraf tay nahi hoti. BMC Pediatrics (2019) me Nepal ke 995 navjaat bachchon par cluster-randomized trial hua - 500 ko sarson ka tel, 495 ko sunflower tel. Laali, rash aur rookhepan me dono groups ke beech koi saarthak farak nahi mila; teenon 14ve din tak badhe aur 28ve din tak wapas kam ho gaye, aur khuli rookhi twacha waise bhi kam hi dikhi - lekhak iski wajah wahan ki 80-95% nami batate hain. Sunflower tel ka bas itna faayda dikha ki skin pH thoda tezi se gira. Do baatein dhyan me rakhein: us trial me sarson ke tel ki tulna doosre tel se ki gayi thi, 'tel na lagane' se nahi, aur wo sardi ki rookhi twacha par tha hi nahi. Nuksaan wala jo ek nateeja hai - ki sarson ka tel twacha ki barrier ki marammat rok deta hai aur microscope me nuksaan dikha - wo Acta Paediatrica (2002) ka chuhon par kiya gaya adhyayan hai, insaanon par nahi. Yani na koi human trial yeh kehta hai ki sarson ka tel sardi ki rookhi twacha me faayda karta hai, na koi yeh sabit karta hai ki badon ki twacha ko nuksaan karta hai. Isi wajah se hum ise chhote bachchon par nahi rakhte - jahan aankda hai wahan faayda shunya tha aur khatre ka ishara maujood hai. Rookhi twacha ke liye jo cheez saboot ke saath aati hai wo saada hai: nahane ke turant baad geeli twacha par moisturiser ya emollient - yahi healthdirect aur Better Health Channel kehte hain.

Research has looked here, but it does not settle the question either way. A cluster-randomized trial in BMC Pediatrics (2019) followed 995 newborns in Nepal - 500 massaged with mustard oil, 495 with sunflower oil. It found no significant difference between the two oils for redness, rash or dryness; scores for all three worsened up to day 14 and then improved again by day 28 in both groups, and outright dryness was rare throughout, which the authors put down to the 80-95% humidity where the trial ran. The only edge for sunflower oil was that skin pH fell slightly faster. Two limits matter: that trial compared two oils in newborns rather than mustard oil against no oil, and it was not about winter dry skin at all. The one finding of actual harm - that mustard oil delayed skin barrier repair, with damage visible under an electron microscope - comes from a 2002 Acta Paediatrica study in mice, not in people. So no human trial shows mustard oil helps winter dry skin, and none establishes that it harms adult skin either. That is why we keep it away from small children: where there is data the benefit was zero and a harm signal exists. What does carry evidence for dry skin is separate and plain: a moisturiser or emollient applied to damp skin right after bathing, which is what healthdirect and the Better Health Channel advise.
