I have not had a cold since 2019.In 2018 somebody recommended taking Black Elderberry Syrup .The company that makes it is in Italy but I buy it from a Distributor in North Carolina.I take one teaspoon every morning.The guy who told me about this product also takes one teaspoon but his wife takes two.
When Nurse Toby first heard of this she refused to use it .After I used it for 6 months and she saw that it worked she began taking it.
Prior to 2019 whenever I had a cold I would take the following which always worked for me :juice from a lemon added to 1/2 cup warm water,
3 tablespoons of honey,a pinch of salt and drink fast.My daughters use this when they get colds.
My parents used the following going back to the 1920’s:
Glass of warm milk with honey and whiskey.They termed this a gugle mugle.
