ASTHMA is defined in the dictionary as being a disease characterised by recurring attacks of difficulty in breathing, and the causes are stated to include the inhalation of dust, or the odour of plants, flowers or animals.
Hay fever is a similar condition and this too, is caused by plants, usually at the time of flowering, when large quantities of pollen are produced.
