>Perika is WS 5572 extract which contains a minimum 3 % hyperforin content. If LI-160 also contains minimum 3% hyperforin, whats the difference??
Hello Mike. It's hard to find anyone who has done real well with St Johnswort. Plenty of clinical studies show it to be effective in mild to moderate depression, but I think the jury is still out on major depression. Don't know if it has any effect on social phobia. I too think the standard 900mg dose is probably way too low, and thus the general lack of enthusiasm about it among folks who really need a precrip.

> Hyperforin has recently been suspected as being the MAOI ingredient of St Johns. I read a study that showed high hyperforin content St Johns was far superior to low hyperforin, and that hypericin had little effect by itself. Lictwer answered my email question on this very issue. They said studies haven't conclusively proved that hyperforin is that important, but that the blend of various compounds in St Johns is...hyperforin being one of those compounds. They stressed to me that all the compounds are needed to work synergistically and that only LI 160 (Kira) has been designed and clinically tested that way. They also said though that if hyperforin is important to me, LI 160 has 3% to 5% hyperforin, which is high.

Personally I believe there are many ingredients of unknown mechanism in St Johns, and that hyperforin is a major player among them. Just an opinion. So I would favor Kira as a first choice because of its track record, and Perika as a second choice as it attempts to jump on the bandwagon. All others probably vary too much from one batch to the next, with only hypericin being the standard focus. No telling really what you're getting each purchase. With Kira or Perika you know you're getting the same thing each time.

I think the risk of photosensitivity is only at doses higher than we could possibly consume. The exception being certain ethnic groups or folks with very fair skin complexion. St Johns is always an interesting topic, and I can't wait to see some results of long term studies of it in major depression.
