Gathering old wives tales

Rosemary is the herb of 'rememberance'
sprigs are often carried at country funerals
quote from 'Hamlet' William Shakesphere
'Theres's Rosemary, thats's for rememberance; Pray you love, remember.

 

The Saxa salt tub had a saying on it.

"Eat a sack of salt with a friend, you'll have a drinking partner for life,"

I think you would be sick or dead long before you could do that, though it didn't say over what time period you were supposed to do it.
