White Oak
- Parts of the white oak, such as the bark and leaves, have been used in herbal preparations for their soothing properties, often in teas and infusions.*
- Quercus alba is a deciduous tree characterized by its lobed, pale gray bark and broad, rounded crown. Native to eastern North America, it thrives in well-drained, acidic to neutral soils, often found in forests and woodlands.
- White oak has extremely durable wood, which has been prized for centuries in shipbuilding, furniture-making, and barrel production for aging spirits like whiskey.

Suggested Use of Herbal Extracts
step 1
Shake well.
step 2
Measure 2 ml. This is approximately 2x droppers, 40 drops, OR a quarter-size amount on a spoon.
step 3
Option A — Place extract under tongue, hold for a few seconds, and swallow with a few drinks of water.
Option B — Place extract in 2-4 oz of water and drink.
step 4
Repeat 2-4 times per day. Herbal extracts are most effective when taken between meals.
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.

Common Questions
No. Most herbs have multiple benefits; however, we can only list one wellness category on the label. Our team spent extensive time researching herbal benefits to assign wellness categories, but they aren't perfect. If you find an herbal product that works well for your needs, keep using it!
Nutritional Resources utilizes a unique, multi-step process to manufacture herbal extracts. First, the herbs are dried. Then, they are extracted in glycerin/water mixture.
The next step is a pressurization process which captures the aromatic components of the herbs. In this step, the use of glycerin, instead of alcohol, is especially valuable. Alcohol dissolves volatile oils and destroys some of their therapeutic qualities, while glycerin captures volatile oils and allows them to remain intact.
Finally, a boiling water extract is made to capture the remaining trace minerals, plus many of the bitter and astringent compounds which require heat to break them free from the plant fibers.
Although the process takes more time, we feel it is worthwhile to create a more complete herbal extract than a simple extract alone.
No, due to limited resources, we do not grow our own herbs. We would love to expand our business in the future, but for now, we will stick to what we do best - converting dry herbs to herbal extracts. We use only three trustworthy sources for all of our dry herb purchases and each herb includes a certificate of analysis.
All herbal extracts use organic vegetable glycerin. The herbs we use are either organic or wildharvested. We will always select organic over wildharvested; however, approximately 15% of our herbs are only available wildharvested.
Herbal extracts are naturally gluten free. Additionally, they are produced in a gluten-free facility.
