Tetanus is an infectious disease caused by contamination of wounds with the bacteria Clostridium tetani, and/or the spores they produce that live in the soil and animal feces.Tetanus has been recognized for centuries. Local tetanus manifests with muscle spasms at or near the wound that has been infected with the bacteria. 2  Cephalic tetanus primarily affects one or several muscles in the face rapidly (in one to two days) after a head injury or ear infection.
Coumarin is a natural flavouring and fragrant substance contained in many plants. It is contained in relatively high concentrations in varieties of cinnamon collectively known as âCassia cinnamonâ and also, for example, in woodruff, tonka beans and melilot.
But Mexico was still known as the home of the world's best vanilla, so the producers didn't admit what they were doing. They disguised the artificial taste by adding coumarin, an extract of the tonka bean, Dipteryx odorata. Coumarin tastes and smells just like vanilla, only more so.ost of the vanilla sold in Mexico is synthetic, though it doesn't all have coumarin in it. Telltale signs of the fake stuff: clear, or dark and murky (the real stuff is amber colored and translucent), low alcohol content (genuine vanilla extract contains at least 35% ethyl alcohol), laughably low price.
