Smell TB

Historical evidence:

Caelius Aurelius (Roman physician 130 B.C.)

“Many subject the purulent sputa to diagnostic tests they place the
phlegm over hot coals and note its odor when it has burned; for a foul
odor always characterizes the product of physical decomposition.”

Hippocrates (Greek physician 460-410 BC)

“In persons affected with phthisis, if the sputa which they cough up
have a heavy smell when poured upon coals,
and if the hairs of the head fall off, the case will prove fatal.”

Traditional Chinese healers diagnosed TB by smelling the
patient's saliva as it evaporates over a flame.

The Dutch word for tuberculosis is tering, which translates
roughly as ‘the process of developing the smell of tar’.
