Here is the quote conderning wine for the choking man from the same article, -page 12:


"You should know then, that first of all a thing, such as wine or
carrion, may be pronounced unlawful from its very nature. What I
mean by 'its very nature' is that the cause of its being pronounced
unlawful is a quality inherent in it. Intoxication and death. If we were
asked concerning these two things, we would not hesitate to say
that they were absolutely unlawful, and would in no way think of
allowing carrion to be eaten in time of desperation, nor ever think
of permitting the drinking of wine when a person starts to choke
over a mouthful of food and finds nothing with which to swallow it
besides wine."
