Last Friday, we were waiting out on the zagúan (porch) of la Presidencia in Tzintzuntzan (sort of our county seat), while the young couple to whose wedding we'd been invited filled out sheaves of papeleo or paperwork.
A vendor carring a cloth bag came up to us and made his quiet pitch for the medicinal and beneficial qualities of the large, black "huesos", or seeds in plastic bags.
The huesos came from the unusual looking plátanos he carried to demo his spiel. Ten seeds in a liter of water was said to benefit the kidneys and alleviate other organs' ailments. A bag would suffice for a month or more of treatments.
I passed up this unusual health opportunity, as I am saving my pesos for three bottles of El Tónico Nervi-Oxin. There's a truck that drives up into our rancho at irregular intervals. His spiel is loud and persistent. I'm just about convinced that Nervi-Oxin will help me sleep better, settle my stomach, etc. One hundred pesos gets you three bottles of that wonder tonic, which seems to cure everything. I'd give it a try if I could get a sample or demo bottle.
I collect various gritos or spiels from the mobile vendors, but I didn't get a decent recording of the Nervi-Oxin guy. I'll try again and when I can figure out how to upload it, I'll do so for my blog audience's listening pleasure.
If I do take that tonic, I'll give a thorough review of its eficacy. (I'm guessing that the número uno ingrediente, after water, is alcohol.)
