Congratulations on 'becoming a believer' in Natural Healing...and welcome to Curezone (I see this is your very first post!). Undoubtedly, there is no greater teacher than Dr. Schulze...and certainly nothing more beneficial than truly natural health & healing!
Interestingly enough, I've recently been contacted by Dr. Schulze (here: http://curezone.com/forums/am.asp?i=1800575). And after he emailed we had a fantastic (long!) chat and started the groundwork/brainstorming for future forum projects together.
He didn't know I had an Herbal Apothecary when we first spoke, but when I mentioned it, he was extremely positive (I can't remember exactly what he said, but it was something like "there needs to be more good quality products out there!"). And then that led to us talking about 'herbal quality' and he explained how he was working directly with growers creating & ensuring the most effective herbs available to anyone in the world (for example, he's been researching and working with his team/growers to create a better mulch for his Echinacea purpurea that will ensure the plants have the highest levels of therapeutic phytochemicals of any Echinacea in the world! And that's just one of the herbs we spoke of...wow!).
Bottom line? After talking with Dr. Schulze and learning just how much time, money and diligent effort (and research) he still puts in to providing the purest & highest quality herbs available in the world, it would be plain-wrong of me (or anyone else) to use his OWN forum to talk about their "Dr. Schulze equivalents" (something I have done occasionally in the recent past, and several others have done for many years). I have my own forum/website for that, and so do all the others.
Besides, if his IF#1 is working well for you, there's not that much difference in cost at all between his and what anybody else creates & sells...so don't cheat yourself & your colon over a few dollars for a bottle of IF#1 !
Dr. Schulze has always been big on creating your own herbal products (and I can attest, there's really nothing more empowering than being your own supplier!). From his original Save Your Life course, here is his original formula for making IF#1:
>>>Take 2 parts - Curacao and Cape Aloe Leaf (and if NOT available, then use 1 part - Buckthorn Bark or 2 parts - Turkey Rhubarb Root), 1 part - Senna Leaves and Pods (start with 1/2 part), 1 part - Cascara Sagrada Aged Bark (start with 1/2 part), 1 part - Barberry Root Bark, 1 part - Ginger Root (or Peppermint Leaf or Fennel), 1 part - Garlic Bulb (or Golden Seal Root), & 1 part - Cayenne Pepper (the HOTTEST is the BEST).<<<
