I didn't realize you were such a herbalist my contrarian friend. Silver and oleander have both been used by natural healers for thousands of years. Oleander dates back at least 5000 years. Kind of predates the allopaths of the last 150 years by a wee bit.
You're just an old alpha dog with a thorn in your paw (or somewhere else) and determined to snap and bite at anyone who comes near. I've taken up for your mangy butt too many times for you to start taking nips at me - so go lick your wounds and behave!
