What about kids?

Herbal extracts are safe and effective for all ages. It is best to err on side of caution when introducing a new product to children. There are two common formulas to calculate smaller doses for your kids.

Fried’s Rule: Take the child’s age in months, divided by 150, then multiply by the adult dose.

Clark’s Rule: Take the child’s weight in pounds, divided by 150, then multiplied by the adult dose.

Example with Fried's Rule: The child just turned 9 years old (9 x 12 = 108 months old). 108 divided by 150 equals 0.72. So the child would take approximately 1.44 ml (or 29 drops).

Alcohol-Free ... Always

Nutritional Resources does not use alcohol to create herbal extracts. Instead we use glycerin which preserves the integrity and concentration of the herbs while providing a pleasant, sweet taste.

We use organic vegetable glycerin as the extracting solvent for all herbal extracts.
