Charles Harrison Blackley Charles Harrison Blackley Charles Harrison Blackley (5 April 1820 – 4 September 1900) was the discoverer of the mechanism behind allergic rhinitis caused by pollen, commonly called hay fever. The isolation of hay fever as a condition had been known since 1819 through the work of John Bostock. Blackley was the first to connect pollen to the condition, and though he held some later discredited views, his insight was an important step in the research of allergens. His most important work was a book titled the "Experimental Researches on the Causes and Nature of Catarrhus aestivus", published in 1873. Charles
Rhinitis with alcohol-induced rhinitis. It is suggested that this variant metabolizes ethanol to acetaldehyde too quickly for further processing by ALDH2 and thereby leads to the accumulation of acetaldehyde and rhinitis symptoms. In these cases, alcohol-induced rhinitis may be of the "mixed rhinitis" type and, it seems likely, most cases of alcohol-induced rhinitis in non-Asian populations reflect true allergic response to the non-ethanol and/or contaminants in alcoholic beverages, particularly when these beverages are wines or beers. Alcohol-exacerbated rhinitis is more frequent in individuals with a history of rhinitis exacerbated by aspirin. Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs), particularly those that
