The remarkable but little known enzyme called serrapeptase (or serrapeptidase, serratio peptidase, or just “the butterfly enzyme”) has been in wide use in Europe and Asia for the better part of 30 years. During that time there have been very few if any reports of side effects in the various scientific studies done mostly in Europe and Asia for serrapeptase, so serrapeptse is considered quite safe. As a result, most of the non-scientific reports you find on serrapeptase conclude that there are “no known side effects.”
The fact is that there have been a few side-effect as reported anecdotally, though side effects are rare.
These reports have included:
* a worsening instead of lessening of pain or edema
* a sudden onset of pain and tight muscles in the legs, knees and ankles
* the sudden appearance of varicose veins; digestive upsets
* increase in blood pressure
* lung congestion problems and even a case or two of pneumonitis.
Curiously, the reported side effects of serrapeptase involve the inverse of some of its strongest benefits. For example, while serrapeptase is known for helping with pain and edema, it’s been reported (anecdotally) to cause these problems.
The reported pulmonary side-effects are especially disappointing, perhaps, since there is so much promise otherwise for improving chronic and longstanding lung problems, and so many positive reports of efficacy for various lung impairments as serious and “incurable” as asbestosis, emphysema, asthma and COPD. This is not to say that serrapeptase isn’t useful and mostly helpful for these conditions, just that there can be the occasional inversion of results.
Unfortunately, it’s not clear whether or not these negative results could possibly be due to what is well-known in the natural and alternative health fields as “healing crises.” Here’s what happens: as the body throws off toxins, they are free to circulate around the body until expelled, and that makes people feel worse temporarily, not better. Sometimes these healing crises retrace the steps a disease or other condition took as it was acquired, or as it developed.
Too, it helps to put these reports into perspective. Any pharmaceutical you can name has a long list of side effects which have shown up in clinical studies to such an extent that they must be reported to alert or warn the public, although for most drugs, only a few of usually many side effects are published in the drug’s insert material.
By comparison, in the case of the reports of serripeptidase side effects to date, they are rare enough that they are anecdotally reported rather than routine occurrences, and they seem both mild and easy to eliminate by not taking the supplement any more.
Of course, it’s always better to be safe than sorry, and to proceed carefully enough with dosage to be able to self-correct if one encounters negative effects while taking serrapeptase. So many people have had no problems whatsoever while enjoying results ranging from good to fabulous to miraculous, that most people would consider giving serrapaptae a try, even if a somewhat cautious try.
