A 28 March 2020 post by Hakim M. Salim Khan M.D. (M.A.) M.H. F.G.N.I. D.O. Principal of the College of Medicine and Healing Arts on his website said,

“We often hear on the news and through the health services that the most vulnerable people to Covid-19 are, for example:

  1. Those with heart diseases.

  2. Those with lung and respiratory diseases.

  3. Those with weak/compromised immune systems.

  4. The elderly.

Congruent with this, Unani Tibb: Whole-Person Healthcare and Medicine can provide further insight using the time-tested wisdom-based understanding of the four temperaments.

Each person is assessed according to their own unique, individual combination of energetic qualities (the above diagram shows each category of temperament, the season it corresponds to, and its energetic qualities.)

According to this understanding, flu-like symptoms are usually the result of a temperamentally cold condition.  This means that those with Phlegmatic (winter) and Melancholic (autumn) temperaments need to take extra care when it comes to diseases of this nature.”
