Santo Domingo, Dominican Republic - I don’t know what it is, but it seems that Dominicans are always coming up with all kinds of remedies for sexual potency. This time we found this product called “La Piedra” (The Stone), which at first was claimed to be a replacement for the well known Viagra, but then later was confirmed that instead of being a stimulant, is a retardant (meaning that if you can’t get it up, you need to look elsewhere), enabling you to hold an erection all-night long (Antre!!!!). The product is sold in Dominican markets in a transparent plastic bag, with a small piece of paper with instructions. It retails for RD$100-$200 Pesos (US$3 – 6).  It appears to be the same product called “El Chinito”, which is popular in Dominican urban culture for the last 30 years. Now, I will caution you; It is said that the one of the ingredients is a resin derived from Marihuana, so don’t try to bring it back to the States.
