Indole-3-Carbinol (I3C) is a phytochemical found in cruciferous vegetables like broccoli and cabbage. This compound has many benefits, with hormone balancing being the most studied. However what caught my attention a few years ago was that a clinical study showed it was effective at inhibiting the virus from reproducing.

Human and monkey cells were infected with a strain of the virus resistant to Aciclovir. I3C showed that it was able to block reproduction of the virus by up to 99.9%. This was fantastic news, I had found the holy grail to curing my pests for good, or at least keep them under control without resorting to prescription drugs. At the time I was suffering from another outbreak and usually dive deep into the web to find the next best cure!

I immediately headed down to the drug store to obtain my bottle of I3C made by Solal. I remember thinking it was quite pricey, especially when added to the growing list of chemicals (the bottled "nutrients") I take to try prevent my outbreaks. But if something worked effectively and was safe, I would sell the house to get it! Hopefully it never comes to that :)

5 months on I3C, and sadly I noticed no benefit. I had 2 or 3 outbreaks during that time and the recovery period was the same. 2 weeks of pain, embarrassment and disappointment. I think any placebo effect had been washed out by my pessimism in constant failure with the countless supplements, herbs and remedies I've tried. I really thought this one would work though.

I'm sorry I can't offer better news regarding this compound, but I suggest leaving this one on the shelf. It's proven all the time that lab results don't always hold up in the real world and I3C treating HSV is no different I'm afraid. If you've had a different experience I'd be glad to hear it!

I've been using it for a year and it started working almost immediately at 400mg daily. I would highly recommend trying it. It may not work for everyone but thats how these things go.
