Recipe for immune-boosting bitters
1 tbsp. honey
1 oz. dried astragalus root
1 oz. dried angelica root
1/2 oz. dried chamomile
1 tsp. dried ginger
1 tsp. dried orange peel
1 cinnamon stick
1 tsp. cardamom seeds
10 oz. alcohol (recommended: 100 proof vodka)
Dissolve the honey in 2 teaspoons of boiling water. Let cool.
Combine the honey and the next 7 ingredients in a mason jar and pour alcohol on top.
Seal tightly and store the bitters in a cool, dark place.
Let the bitters infuse until the desired strength is reached, about 2-4 weeks. Shake the jars regularly (about once per day).
When ready, strain the bitters through a muslin cheesecloth or coffee filter. Store the strained bitters in an airtight container at room temperature.
To use: Mix this tonic into hot tea or take a few drops as is first thing when you wake up for protection during cold and flu season.
Don't take if you are pregnant.
I take a 500 mg Turmeric (Curcumin) daily. Great anti-inflammatory. Ginger root also is good. Camomile Tea is great for calming you down. My daughter has an anxiety disorder and it helped her sleep at night.You can grow it and dry the flowers. It spreads.
