Old Wives’ Tales, Grannies’ Wisdom, etc., are in reality the sum total of hundreds of centuries of anecdotal evidence passed down throughout those years. It is often eventually shown that such do indeed have some scientific basis.
Cold Liver oil, an old treatment for Rheumatoid Arthritis, was eventually shown to have within it a compound that inhibits Cox2 just as do the latest NSAIDs and appears less prone to cause side effects or promote adverse cardiac events than synthetic Cox2 inhibitors. So, I never discard out of hand any Old Wives’ Tales or Grannies’ Wisdom ‘cos more often than not there is a truth of some kind at the heart of them
