Thomas Withers (1750-1809) was a physician to the New York County Hospital. Like Cullen, he believed asthma started in the mind and resulted in convulsions of the fibres that wrap around the lungs. He believed in the nervous theory of asthma and in the convulsive theory of asthma. (1, page 75)
In a review on Wither's book, Tobias George Smollettt, in 1786, compared him with John Floyer, who is considered by many to be the father of the convulsive theory of asthma. Smollet said:
'This is an old building, with a modern front and fashionable ornaments: in other words, it is the valuable work of Floyer, with explanations from the modern nervous papathology. Dr. Withers, in his former works, adhered so closely to his master's precepts, almost to his words, that we did not expect any thing new. (2, pages 17-18)Smollet continued:
We hoped, indeed, that experience might have opened sources of enquiry, which his unwearied diligence would have pursued; but the little which is his own, is not of the best kind. The account of the asthma, as may be expected, when we consider the sources, is clear, intelligible, and judicious: the cafes are sometimes unnecessarily minute, at others imperfect; they arc in general very trifling, and the effects of remedies unreasonably exaggerated. (2, page 18)Dr. Withers believed spasmotic asthma was "a nervous disorder accompanied with great irritability of the lungs." Through his various books he provided various pithy examples of cases of asthma he witnessed, along with the remedies used. (3, page 300)
He believed a good remedy for nervous, or spasmotic, asthma was opium, which "diminishes the irritability and spasmotic contraction of the air vessels; mitigates the cough; lessens the pain, anxiety and difficulty of breathing; shortens the duration and the facilitates the cure of the asthmatic fit."
