Apparently nature has already made a “drug” that inhibits the phopholipase enzyme - it’s called flax seed oil (active lignans) and flavonoids (citrus fruit, berries, onions, chocolate, red wine, etc.). See research article below from Archives of Pharmaceutical Research 2004:
Dr. Ji Suk Lee, et al, Inhibition of enzyme phopholipase by lignans and flavans, J. of Pharm. Res., Vol. 27, No. 10, 1043-1047, 2004:

Yep....loads of research of lignans! Also ...Fermented Wheat Germ Extract (Avemar) and Modified Citrus Pectin (Pectasol) have been well researched. We use them all in the clinic I manage...depending on the patient need, of course ;)
