I've got 10mls of this capsicum concentrate, most of which I will never use. Want a 3ml bottle to try out? I don't mind sending it to you. Just PM your address. Use at your own risk though LOL
I will let you know how the recipe turns out.
I did some light research on capsicum properties and medicinal uses/applications before I purchased the concentrate. It is apparently used in a very diluted form in the nasal cavity for quick absorption for things like headaches (who knew!?) So, while this is not the exact same as inhalation into and absorption by the lungs, it is apparently safe for mucous membranes - EDIT safe in a very low, diluted amount.
Also, the vendor I purchased from, High Desert Vapes, says this:
"Capsicum. Scoville heat units (SHU) 15,000,000. Ingredients: Natural Capsicum Hot Pepper. USP Kosher Grade. Usage Rate Varies. All Flavoring Diacetyl Free! No Refunds on Flavoring. Precaution: Avoid contact with eyes or open wounds and before using. Always be sure to wash your hands thoroughly after usage. If taken orally in large doses, capsicum may cause stomach upset, vomiting, and ........."
I did read somewhere that 1 drop per 5ml can add some nice, but tolerable heat. But, don't quote me on that. I would start with very small amts. EDIT ~ Okay, I just read 1 drop per 10mls is strong and someone else used a 1% 1:20 dilution rate and it's still strong. I'm going to dilute mine before using it in any recipe just to be safe.
