not expensive at all
"Is this fair enough?' asks n202 ----
If your stuff is better tasting than my grandma's Chicken Noodle Soup and you can devise a safe protocol that allows you to eliminate all colds from an entire elementary school in your town this spring, I would say you might pass the preliminary. The final test, for the million $$$, would be to eliminate colds from another entire elementary school this fall. (It would have to be another school, since the first school kids would already now be taking your formula regularly, since it worked so well).
Keep in mind, the parents might raise some objection to their kids taking your concoction at all. I would imagine the school nurse might object as well, plus the local health department could intervene and disrupt your plans, too.
For that matter, how did you get your relatives to agree? Have they all been cold-free since taking your home-made prevention?
(anecdotal, but we're curious anyway to know those results).
Keep in mind, I can't even get my 12-year old son to take Sambucol, despite what I perceive to be its benefits (I have not had a cold in 17 years, since taking a daily dose after I first discovered it while living in Israel).
Does your brew also stop allergic symptoms?
Again, I am curious, what does it taste like?
