A renowned commentator, a great thinker of Ummah, Mufti Ahmad Yar Khan عَـلَيْهِ رَحْـمَةُ الْـحَـنَّان has said in his commentary of this Hadees: To breathe into the vessel is an act of animals. Moreover, the breath, sometimes, may be poisonous therefore one should breathe moving the utensil away from the mouth (i.e. to take the glass away from the mouth while breathing). Do not cool down the hot milk or tea by blowing, wait for some time, and drink it when it is a bit cool. (Mirat, vol. 6, pp. 77)

However, there is no harm to blow by reciting any verse of the Quran or Salat-‘Alan-Nabi etc. with the intention  of cure.

Recite ﴿بِسۡـمِ اللّٰهِ﴾ before drinking.

Drink water in small sips as large sips cause liver impairment.

Drink water with the right hand while sitting.

If Wudu is done by taking water in some ewer etc. then drinking the leftover water is a cure of 70 diseases because it resembles water of Zamzam. Besides these two (the leftover water of Wudu and water of Zamzam), it is Makruh to drink any other water whilst standing. (Derived from: Fatawa Razawiyyah, vol. 4, pp. 575; vol. 21, pp. 669)

Drink these two waters whilst standing, facing towards the Qiblah.
