I followed the full Cowden Lyme protocol as found on the Nutramedix site. Nutramedix sells the monthly packages for something like $285.
Cowden claims that some of the herbs in the Lyme protocol address Babesia and Bartonella. I've come to believe that an asymptomatic babesia infection has been impeding my healing from Lyme. I can't say that the Cowden protocol addressed that. I started titrating the Buhner Babesia protocol in mid-July (and am still titrating because I'm taking a bunch of stuff). I'm finally experiencing improvements.
I was able to buy all of the Cowden tinctures on Amazon for almost half what Nutramedix charges. PureFormulas.com sells them for similar prices as Amazon and they offer free shipping. (I learned about
the latter source after I went off Cowden)
You may know that Nutramedix offers financial assistance for one patient per practitioner and I think you can get 6 months' worth of tinctures. There has to be true financial need.
If you only want to treat Lyme, Buhner's protcol is definitely cheaper since he only uses 3 herbs (Japanese Knotweed, Cat's Claw and Eleuthero). However, there are many other herbs he suggests to address specific symptoms and/or support specific organs.
Here's a link to Buhner's preferred source of Cat's Claw and Japanese Knotweed so you can get an idea of prices:greendragonbotanicals.com/products/lyme-related-herbs/
Buhner updated his Lyme protocol recently and the details will be published in his new Lyme book due out at the end of this year. Somehow, I suspect it's more involved.
The co-infection protocols involve many more herbs. I must admit I haven't totaled the cost.
The companies he recommends for herbs charge lower prices overall for their tinctures vs. comparable sizes of Nutramedix tinctures bought through Amazon.
Please let me know if you need further detail.
