Phosphatidylcholine oral and/or enema

So there is some info out there lately that phosphatidylcholine is helpful for UC, especially the enteric coated kind. This, along with some HW anecdotes that people have gone into remission with both oral Phosphatidylcholine, and enemas make me curious. Its not too new, as some of these anecdotes date back several years. Anyway, there are some discrepancies I have some questions about.

OM Says he tried it as an enema, but found it irritating, others accounts Ive read say its entirely non soluble in water, and that it is difficult to administer. OM, any words on how you did it?

This woman says she went into remission on oral phosphatidylcholine:

However the 'word on the street' is that taking it orally will yield no benefit to the colon… So, what gives?

Any other users out there?

Few of these I tried and found irritating. Don't remember which one though. Can't find my posts.
