Just wanted to add in my recent experience.  The day I read a post on 
the CS list about Serrapeptase is the day I ran out to the health food 
store and bought a bottle.   I've been taking 40,000 IU twice a day now 
for almost two weeks.

My personal priority has been my blood 
pressure.   A number of years ago my doctor put me on 25 mg (a modest 
dose) of Toprol XL, a beta blocker.  It did a good job of  bringing my 
blood pressure down from approx. 150/95 down to 120/70.....  Time has 
marched on and I continue to take the stuff as it appears to be a 
lifelong habit once started.   In the last six months I have been paying
 closer attention to my bp, discovering that it has gradually continued 
to worsen and was around 160/95 approx. occasionally going 'much 
higher.'

I was worried about it but hadn't yet
 gone to my doc for an increase to my prescription.  This was my frame of mind 
when I started taking this supplement.

It's
 been about two weeks now, and in the last few days I have seen numbers 
regularly in the 140's/ 80's.  This morning I came in at 136/80.

I
 know this is unreliable anectdotal evidence, but it's pretty compelling
 to me.  I think the Serrapeptase is doing its job for me!

I am indebted to the silver list.  Without this tip I know what direction I 
would have been headed.  I think I'm now on the right path.

Yesterday,
 my mail order arrived, with a bottle of 90 capsules of 120,000 iu 
each.   I won't be taking more than one of THESE capsules a day.
