BĀD (2)


BĀD (wind) in Perso-Islamic medicine: 1. wind as a medically relevant environmental factor; 2. “airiness” as internal physiological and pathological agent.

1. Following Hippocrates’ “On airs, waters, places,” Galen stressed the influence on human health of wind as of other ecological and climatic factors; the winds prevailing in a given locality were held to affect the temperament of its population, and more specifically, to transmit those miasmatic diseases thought to be caused by corrupted air or vapors. Each wind had certain characteristics ascribed to it, depending on changes of season or time of day, and some were considered more salubrious than others. In Arabic and Persian medical literature, wind as an external force acting on the organism was treated together with air in the discussion of the six non-naturals (setta żarūrīya).

2. In Galenic medicine, air entered the lungs through respiration and was there and in the left ventricle of the heart assimilated to the body as vital spirit (pneuma zōtikon, mistranslated into Arabic as rūḥ ḥayawānī), which arterial blood then carried throughout the body. For Galen this pneuma was not a substance, but a certain quality of the inhaled air, yet he also used the term pneuma to denote pathologically altered matter which, because of its mobility, sudden formation, and dissolution within the body, could not be understood as fluid or solid. According to this concept, pneuma in Galenic medicine did not only include flatulence in the gastrointestinal tract and its symptoms, such as eructation or colic-like aches, but was taken to act, in a variety of ways, on bone and muscle tissues as well as on organs like the brain, eyes, ears, spleen, and uterus. Manifestations of excess wind included disorders as diverse as epilepsy, pannus trachomatosus, earaches, splenomegaly, tympanitic dropsy, uterine swelling, and spontaneous abortion during the first three months of pregnancy, “phlegmatic tumors,” bone fractures and spinal tuberculosis(?); male impotence without an apparent deficiency of semen production was, conversely, thought to derive from a lack of “wind” and was to be treated by ingesting flatulence-inducing foods such as beans. In the Greek authors down to Paul of Aegina, there is no terminological differentiation between pneuma as a force of life and pneuma as a gaseous substance analogous to fluids and solids on the one hand and to the four humors on the other; often, pneuma is the product of disordered humors like phlegm and black bile. In the Arabic versions of the Greek texts, and consequently also in Persian medical literature, the ambivalence of pneuma no longer obtains; pneuma as a force of life is rendered as rūḥ (spirit), whereas airiness as a material component of the body becomes rīḥ or bād (wind); following Galen, it is often qualified as coarse (ḡalīẓa) when discussed as an agent of internal disorder. Wind, although frequently mentioned as a cause of disease different from the four humors and not just as the result of their pathological alteration, was never really incorporated into the system of humoral pathology. Ebn Sīnā (Avicenna) apparently was the first to list internal wind under a separate heading in his discussion of pain according to its causes, and Esmāʿīl Jorjānī then adopted this classification. The exact place of wind in Arabic and Persian medical writing remains to be examined, however, in particular as regards the possible influence of popular notions on the development of Islamic Galenic concepts of wind. As early as in Ebn Māsawayh’s treatise on ophthalmology, Daḡal al-ʿayn, pannus trachomatosus was called rīḥ al-sabal, and the Persian term bāḏ-e baḵast (fly-wind) appeared there as the current name of a symptom which the author related to night blindness. In a later non-specialist usage, bād reflects several vague notions about disease, not all of them necessarily derived from Galenic medicine either; a sudden onslaught of pain is implied in some (Farhang-e fārsī I, pp. 435-36 and ʿA. A. Nafīsī Nāẓem-al-Aṭebbāʾ, Farhang-e Nafīsī I, Tehran, 1355 Š./1976, pp. 498, 502, 503, s. vv. bād, bād-e sorḵ [erysipelas], bād-e gonjī [colic], bād-e fatq [hernia], etc.).
