My hot lemon and honey drinks can eat thru plate metal like Alien blood!
I'm not sure that Speicher is suffin with cold but a tip passed down from my Grandfather is, at the first signs of a heavy cold, count out twenty peppercorns and then pop them in your gob really mash and chew them up, then wash them down with water.
I will admit to being somewhat reticent to try this medicine but then he swore by it's properties for seeing off a cold.
