Berberine: the power of color and bitter flavor

By Tammera J. Karr, PhD, BCHN, CNW, CDSP, CGP

How often do we connect flavor, color, and historical use of foods and herbs to wellness? Our choices are frequently unconscious, reflexive and based on convenience. For centuries, cultures have utilized natural compounds daily or seasonally for wellness. In Asian gastronomy, the selection of spices and foods involves far more color and flavors Westerners shy away from – bitter, dry and astringent.

Current science is expanding our understanding of traditional foods, herbs and gastronomy. Each year, more research supports what American Indian elders from the Pacific Northwest Nations have known about Oregon Grape’s health benefits for generations. Equally, the power of the Asian cultural herb turmeric and spices has been repeatedly documented in PubMed for an expansive list of health challenges. What do these two herbs have in common?

In the Pacific Northwest, the Oregon grape, a prickly low shrub, has been used in native gastronomy for over a millennium. From the pioneer’s perspective, the dark purple berries with a rich grape flavor were the only edible portion of the plant. High quantities of sugar were used to mask the astringency of the juice, which, like elderberry juice, contains high levels of polyphenols, vitamin C, tannins, and cyanidins. In contrast, for First Peoples, the bright yellow flowers, root, layer just under the bark and the bitter compounds of the leaves and flowers provided the actual value. Native Americans used concoctions, decoctions, and infusions of Oregon grape plant parts to treat a wide variety of human ailments, including syphilis, arthritis, and itchy eyes.  Oregon grape is a medicinal herb from the Berberidaceae plant family. It has a long history of use for skin irritations, indigestion, arthritis, and stomach ulcers from h.Pylori. Oregon grape, European Barberry, Goldenseal, Chinese Goldthread and Turmeric share a significant bioactive compound called berberine. This natural plant extract gives the Oregon grape and Turmeric its yellow color and anti-inflammatory, antimicrobial, and antioxidant properties.

Common foods containing berberine are barley, oats, wheat, barberry, and cranberries. Cooking or processing berberine-containing edible foods reduces their berberine content. For the most berberine benefit, consume in raw or minimally processed forms.

Berberine is an isoquinoline alkaloid with many pharmacological activities. Berberine is a bitter-tasting and yellow-colored chemical. Traditionally used to strengthen the heartbeat, kill bacteria, regulate blood glucose, and help reduce swelling. Berberine supplements are commonly used for diabetes, high cholesterol, fatty liver (metabolic syndrome), and high blood pressure.[1]  Berberine has been a part of Chinese and Ayurvedic medicine for thousands of years.[2] Traditionally, berberine-containing herbs have been used for burns, canker sores, and liver disease.

Berberine is particularly interesting because of its antidiabetic and antioxidant activities based on multiple biochemical pathways.[3]  Studies of berberine show growing efficacy in treating several metabolic health conditions, including diabetes, obesity, heart problems, and gut health.[4] Metabolic disorder is the most common cause of chronic diseases worldwide. There are more than 415 million people with diabetes in the world, and the number is expected to increase to 642 million by 2040.[5],[6]

 

The most notable benefits include:

 

An increase in the production of synthetic berberine. This compound is created in a laboratory and is chemically identical to the natural form found in plants. Synthetic berberine is often used in supplements and medications due to its lower cost and higher purity compared with natural sources. Herbal experts contend that synthetic berberine is not as effective as the natural form with its many synergistic compounds.

Berberine supplements are available through a wide selection of holistic providers and health food stores in 500mg capsules. Consumers can use up to 1,500mg daily, taken throughout the day. A certified or licensed holistic or herbalist provider should be consulted before use. Results show that using berberine for blood sugar support and weight control usually takes 2-3 months.[15]
