Herbal Voltage


Plants, and especially herbs, have been used as electron donors (process of healing) for centuries. Dr. Tennant has selected herbs with a long history of contributing to health as a means of increasing voltage in those with low voltage and chronic disease.

Dr. Tennant has selected a group of herbals that are electron donors and can improve voltage in the body.

Licorice Root

Licorice Root is the world's most widely used herbal remedy. It helps stimulate the adrenal glands and helps prevent the breakdown of adrenal hormones such as cortisol (the body's primary stress-fighting adrenal hormone and anti-inflammatory), making these hormones more available to the body.

It also helps with stress and depression. It acts as an expectorant and has been used to clear the lungs, cleanse the colon, and boost the immune system. It may also enhance immunity with strong anti-viral properties by boosting levels of interferon, a key immune system chemical that fights off attacking viruses.

Red Clover

Red Clover is considered to be one of the richest sources of isoflavones.

Isoflavones are similar in shape to the female hormone estrogen. Therefore, they may attach to estrogen receptors throughout the body and displace estrogen.

Burdock Root

Burdock is best known as a blood purifier and mucilage. It works to help remove toxins through the respiratory, urinary, and lymphatic systems. This detoxifying effect is responsible for many of burdock root’s benefits.

Research has shown that arctigenin, a compound in burdock, “exhibits cytotoxicity by inducing necrosis in cancer cells.” Another compound, arctiin, “demonstrates a strong cytotoxic effect” on hepatoma, lung cancer, ovarian cancer, skin cancer, CNS cancer, and colon cancer.

Burdock root decreases the workload of the immune system by helping it fight bacteria and fungi. Its detoxifying effects help the organs work more efficiently and restore the body’s ability to heal itself.

Burdock root may increase bile production, which cleanses the liver and helps it function better.

Stillingia Root

Stillingia Root is known as a blood purifier and mucilage helping to cleanse. Also known as Queen’s Root, stillingia root, when combined with other depurative herbal remedies, clears the blood by promoting elimination (particularly prickly ash).

Stillingia root’s diaphoretic properties (promotes sweating) help to remove and clear toxins from the body through the skin. It is also believed to be quite effective in ridding the system of the toxic effects of chemotherapy treatments. It also helps bowels to move more efficiently.

Berberis Root (Barberry Root Bark)

Berberis Root, also known as Barberry Root Bark, contains an alkaloid, berbamine, a known antibacterial, astringent, and anesthetic that helps reduce inflammation.

It has been found to be useful in treating hepatitis and rheumatoid arthritis. It is a liver cleanser known for promoting the flow of bile in the liver and acts as a laxative. Berberis root has also been used for treating problems with the spleen.

Poke Root

Poke Root is a powerful cleansing agent used to help decongest the lymphatic system. Supporting the lymphatic system is basic in most anti-cancer treatments as well as cleansing programs for a whole range of health problems.

Poke Root has traditionally been used to treat advanced rheumatism, respiratory disease, or auto-immunity issues. Poke Root has been shown to boost the immune system through its interaction with the proliferation of T-cells.

Cáscara Sagrada – California Buckthorn bark

Also known as Rhamnus purshiana, Cáscara sagrada is Spanish for “sacred bark” and was used for centuries by Native Americans for its laxative effects at higher doses.

Cáscara sagrada contains compounds called anthroquinones that are responsible for cáscara's purgative effects. Anthraquinone may have cancer fighting properties, but little formal scientific evidence is available.

Prickly Ash Bark

Southern Prickly Ash and the Prickly Ash of the north are both excellent immuno-stimulants, helping to stimulate the adaptive immune system when it is needed to fight infection and pathogenic bacteria, or to increase scavenging activity in the blood to clean up waste products.

They have also been shown to be excellent in increasing peripheral circulation. They are warming in nature and ares commonly used for Reynaud’s disease.

Buckthorn Bark

Buckthorn, also known as Black Alder, contains the ingredient anthraquinone. Buckthorn is also used as a health tonic and was traditionally used as a "blood purifier" and diuretic.

Like cáscara sagrada, it does act as a purgative.

Indian Rhubarb Root (Rheum officinale)

Used traditionally in small amounts, this herb acts as a gentle laxative and helps purge the liver of toxic buildup and waste. It helps neutralize acids and reduce inflammation.

Its malic acid also carries oxygen to all parts of the body, aiding in healing and promoting a positive and balancing effect upon the whole body.

Sheep Sorrell

René Caisse, who popularized Essiac tea as a cancer cure, felt Sheep Sorrel was the most active cancer fighter among all the herbs present in her formula.

Sheep sorrell is a known anti-inflammatory agent. Because of their high vitamin C content, sorrel preparations are also recommended as a preventive for scurvy, a condition caused by a deficiency of the vitamin. Tea made from sorrel plant roots is used in herbal medicine as well.

Sheep sorrel contains antioxidant flavonoids that help remove potentially damaging free radicals from your body.

Slippery Elm Bark

Slippery Elm got its name when Native Americans discovered that when the inner bark is mixed with water, it generates a thick and slippery gruel full of mucilage, hence the ‘slippery.’

The mucilage does a good job of soothing and coating the mouth, throat, stomach, and intestines, causing much relief from things like gastroesophageal reflux disease (GERD), Crohn’s Disease, ulcerative colitis, diarrhea, diverticulitis, and irritable bowel syndrome (IBS).


Watercress is heavy in antioxidants, a key ingredient in the prevention of disease such as cancer. Watercress is very rich in glucosinolates, which are water soluble phytochemicals that contain sulfur.

Natural herbalists have used watercress as a blood purifier with system cleansing properties that help to clear toxins from the body. Because it is high in potassium, it is strongly alkaline and considered to be useful in treating acidity and inflammation, as well as for purifying the blood.

Blessed Thistle

Blessed Thistle is a depurative, having diuretic and diaphoretic properties; these actions help to purify the system and rid the body of toxins.

Blessed thistle's medicinal actions help give support to the liver and help it to repair itself. It is also a powerful anti-inflammatory.


Start with one capsule per day for one week. Increase the dose to one capsule twice a day the second week, one capsule three times a day for the third week, and one capsule four times a day thereafter until your voltage normalizes or you are instructed to stop.

If you feel tired with detoxing as you increase the dose, you should stay at a lower dose until you feel better before increasing the dose.
