The effects of lobster on some persons and under some conditions are well known.
In order to thoroughly study the effect A. M. Cushing adopted the happy idea of proving the specific lobster poison, and the result has been a very valuable addition to our armamentarium (H. R., iii. 98).
Homarus is an agent of great activity, as the subjoined symptom list will show. Persons have been known to die after eating lobster and thereafter drinking milk.
Cushing put a little of the poison into warm milk, and in ten minutes it was a hard mass. Papoid soon dissolved it, but pepsin took much longer.
Cushing found that milk aggravated his symptoms during the proving. “ From motion; from passing wind; after eating; from inhaling cold air.
L. H. Hallock relates (Med. Adv., xxii. 311) a personal experience. An hour after eating a small amount of lobster salad, general pruritus commenced, worse in lower extremities, especially the calves. The itching was of a biting, burning character, not > by rubbing or scratching, almost unendurable. It lasted two hours in spite of bathing with hot and cold water, fresh and salt. No sooner had the itching abated than lips, nose, eyes began to swell, till the eyes were closed and lips almost completely inverted. Throat swollen and œdematous so that it was almost impossible to breathe; profuse salivation. Eight hours after the meal he had the appearance of a severe and protracted debauch. In twenty-four hours was as well as ever. Once subsequently he had a like experience after eating lobster.
