Did the Buddha really allow raw meat and raw blood for a monk possessed by a spirit?

In Kd 6 , We come across the following:- > On one occasion a monk was possessed by a spirit. His teacher and > preceptor who were nursing him were not able to cure him. He then went > to a pigs’ slaughterhouse to eat raw meat and drink blood. As a > result, he became well. They told the Buddha. > > “For one who is possessed, I allow raw meat and raw blood.” I had never heard of this before. I only encountered it because a polemical blog quoted it in an attempt to criticize Buddhist scripture by highlighting passages that seem negative or problematic when taken at face value. Since their intent of quoting the above was obviously hostile I’d like to understand the background of these from those familiar with the Vinaya:- My questions are: 1. Is the translation accurate? Does the Pali genuinely say that the Buddha allowed raw meat and raw blood in such circumstances? 2. Is this passage considered authentic and canonical within mainstream Theravāda? 3. If both of the above are true, How is this interpreted by traditional Buddhists today? Is it taken literally, regarded as a narrowly defined medicinal or exceptional allowance, or understood in some other way? And if it is accepted, how is it justified within Buddhist ethics and discipline?
