Sounds like systemic enzymes are a very GOOD THING, don't you think?
I feel they are OK for short term use. But I don't like substituting for the body's own production long term due to the risk of shutting down the body's own production. For chronic inflammation I prefer building up the adrenals since the adrenals produce the body's own anti-inflammatory corticosteroids. I also like licorice root and yucca root since they are both great steroidal anti-inflammatories and also both help build the adrenals.
One other note on systemic enzymes. They should be taken on an empty stomach for inflammation so they are not being used up on digesting food.
