Herbs With Claims to Lower Blood Glucose

Herbs With Claims to Lower Blood Glucose

The long-term complications of uncontrolled diabetes are well known – damage to eyes, kidneys, nerves, blood vessels, and other organs. Most of this damage is credited to chronic elevated blood glucose levels. kind II diabetics and pre-diabetics are aware of these dangers and sometimes consider adding herbal therapy, to their doctor prescribed medication, to “tweak” blood sugar lowering effects and possibly prevent complications. Sometimes patients may try herbs and other supplements because they want to use a more “natural” treatment to control their blood sugars.

The strength and measure of herbal products vary and your pharmacist can assist you in selecting products, discussing dosage ranges, and preventing any herb-drug interactions. Herbal products can also vary greatly from batch-to-batch and it is always preferred to buy a quality name brand product that has been assayed and uniform in regard to active ingredient. The bottom line is that there must be some assurance that you are purchasing a product that will consistently deliver a stated measure of active herb.

kind I diabetics who require insulin generally should not add herbs with blood sugar lowering effects to their treatment because of the serious possible for life -threatening hypoglycemia (extremely low blood sugar) or other medical complications.

in spite of of the reasons for using these specific herbs, one must always keep their doctor and pharmacist “in the loop” to prevent any hypoglycemic responses and dangerous or toxic interactions. Hypoglycemic responses are dangerous and can be deadly.

There are several noteworthy herbs that are claimed to have blood sugar lowering effects. These herbs are not generally used in Western herbal medicine and are more shared in Ayurvedic Medicine and Oriental Medicine. The exact mechanism of action in lowering blood sugar is often not known. In addition, these herbs may not work well for everyone and their overall effect may vary in individuals. Side effects can also be patient specific and a combination of these herbs may be required to acquire the desired effect. Commercial herbal combinations are obtainable and often contain antioxidants, zinc, chromium, vanadyl sulfate, and other minerals or vitamins that may be advantageous to diabetics.

Glucometer blood sugar monitoring, especially fasting samples and the two-hour after meal (postprandial) sampling, are usually necessary until blood sugar levels are under control. However, always follow your physician’s advice regarding the frequency of glucometer testing. Hemoglobin A1c values should also be observed by your physician to follow blood glucose levels over the long haul.

Agaricus Mushroom (Agaricus blazei):

This mushroom has shown evidence of lowering blood glucose.

Aloe Vera (Aloe):

Aloe Vera is a member of the Lily family already though it resembles a cactus. There are over 240 species of Aloe, but only four species are recognized as having nutritional value with Aloe barbadensis leading the group.

Preliminary research indicates aloe gel might lower blood glucose levels. measure is usually (15-30 ml (50 mg) per day.

American Ginseng:

A very popular herb in Chinese medicine. Recent studies have shown that Ginseng may be helpful in reducing blood sugar levels in kind II diabetic patients. For diabetes, ginsengosides and possibly other constituents are thought to reduce postprandial glucose levels. This effect might be due to either tissue insulin sensitization or direct stimulation of insulin release or both of these mechanisms. The effect of various ginsengs on glucose appears to be related in part to the mix of ginsenosides. Other non-ginsenoside constituents likely affect blood glucose in addition.

For reducing postprandial glucose levels in patients with kind 2 diabetes, 3-9 grams up to 2-hours before a meal has been used. However, there is no additional assistance to taking more than 3 grams. Other studies suggest taking ginseng 40 minutes prior to meal to acquire the optimal effect. Irregardless, American ginseng should be taken within two hours of a meal to avoid possible hypoglycemia.

Bilberry (Huckleberry):

Bilberry (Vaccinium myrtillus) has been used in traditional European medicine for nearly a thousand years, chiefly to treat diarrhea. Bilberry contains a powerful antioxidant that helps to promote circulation in the eyes. Studies on diabetic dogs have also indicated benefits in reducing blood sugar levels. Use Bilberry uniform at 25% anothocyanins for maximum potency.

Bitter Melon (Momordica charantia):

A member of the Cucurbitaceae family, the plant grows in tropical areas, including parts of the Amazon Basin, Africa, Asia, the Caribbean and South America. The bitter melon grows as a vine bearing green leaves and yellow flowers with oblong green fruit that resemble a cucumber.

Bitter melon has a long history of use as a hypoglycemic agent in Asia, Africa, and Latin America, where the plant extract has been referred to as vegetable insulin. Although several constituents of bitter melon have hypoglycemic similarities, most interest has focused on a polypeptide secluded from the seeds called polypeptide-p and a combination of two steroid glycosides referred to as charantin. at the minimum three different compounds in Bitter Melon have been reported to have sugar-regulating similarities. Gurmarin, in particular, is a polypeptide considered to be similar to bovine insulin.

Blond Psyllium (Blond Plantago):

Blond psyllium seed husk orally seems to considerably reduce postprandial serum glucose, insulin levels, serum total cholesterol, and low-density lipoprotein (LDL) cholesterol levels in patients with kind II diabetes and hypercholesterolemia

Blond psyllium seems to reduce postprandial blood glucose levels by about 14% to 20%, total cholesterol by about 9%, and LDL cholesterol by 13%. Blonde psyllium also seems to lower postprandial glucose levels in patients with kind I diabetes. Blond psyllium’s maximum effect on the glucose levels occurs when psyllium is mixed and consumed with foods. Blond psyllium does not lower postprandial glucose in people who do not have diabetes.

Cinnamon Bark (Cassia Cinnamon):

Cinnamon is getting a lot of attention as a treatment for diabetes. There is preliminary evidence that it can lower blood glucose and cholesterol levels in people with kind 2 diabetes. So far, this assistance has only been found with Cassia Cinnamon (Chinese Cinnamon) in humans. As little as ¼ to ½ teaspoonfuls can have a powerful effect in lowering blood sugar.

Recent studies (2008) indicate that cinnamom may not considerably lower blood glucose.

Devil’s Claw:

Devil’s Claw is native to south and central Africa. Its medicinal value lies in its fleshy roots, which are sliced, chopped, or pulverized while fresh.

Some evidence shows that this herb might decline blood glucose and have additive effects with medication used in diabetes.

Eleuthro (Siberian Ginseng):

Eleuthro is a shrub that grows 3 to 10 feet high with products made from the root. The root contains a combination of elements, shared to many plants but occurring together in Siberian ginseng, called eleutherosides. Among the other elements are chemicals called polysaccharides, which have been found to raise the immune system and lower blood sugar levels in laboratory studies using animals.

Like the panax ginsengs, Siberian ginseng is considered to be an adaptogen, which method that it helps in stressful circumstances and also helps return the body to a normal balance.

Fenugreek (Trigonella foenum-graecum):

measure: 10-15 grams per day in divided doses with meals Fenugreek is effective for lowering postprandial (after meals) blood sugar. The applicable part of fenugreek is the seed. The active constituents include trigonelline, 4-hydroxyisoleucine, and sotolon. About 80% of the total content of free amino acids in the seeds is present as 4-hydroxyisoleucine, which appears to directly stimulate insulin. This effect is glucose dependent and only occurs in the presence of moderate to high glucose concentrations.

Fenugreek seeds have a distinctive bitter taste and odor. Sotolon is frequently used as a flavoring for artificial maple syrup. Theoretically, patients who are allergic to other Fabaceae plants including soybeans, peanuts, and green peas might also be allergic to fenugreek.

Ginger (Zingiber officinale):

Preliminary research indicates ginger might increase insulin levels. Theoretically, it could have an additive effect with medication used to treat diabetes and cause hypoglycemia.

Glucomannan (Konnyaku root):

A member of the yam family, this herb is high in fiber and can help normalize blood sugar, relieve stress on the pancreas.

Gulvel (Tinospora cordifolia):

Grows wild along roadsides throughout the tropical and sub-tropical plains of India and Sri Lanka. Plant extracts causes reduction in fasting blood sugar in rabbits and rats.

Gymnema sylvestre (Gumar):

A tropical plant of the milkweed family with an ancient Sanskrit name meaning “destroyer of sugar.” Preliminary clinical research indicates that certain Gymnema extracts can reduce blood glucose and glycosated hemoglobin (Hb A1c) in kind I and kind II diabetics.

Holy Basil (Hot Basil):

Preliminary evidence indicates that holy leaf extract may decline fasting (17.6%) and postprandial blood glucose in patients with kind II diabetes.

Jambolan (Syzygium cumini):

A close relative of the clove tree Syzygium aromaticum, Jambolan is native to east India and the Malay Peninsula, but has spread as far as China and Australia and is grown in the Caribbean.

Only the bark of the Jambolan has proven medicinal value, although the seeds are often used in addition. In Asian medicine, it is used for diabetes, diarrhea, sore throat, and diseases of the spleen.


Kudzu is native to Japan and China, however it grows extremely well in the Southern United states. This vine, when left uncontrolled, will ultimately grow over almost any fixed object or other vegetation.

Kudzu or its constituents might have hypoglycemic, hypocholesterolemic, and antioxidant activity.

Neem (Azadirachta indica):

Neem is a member of the Mahogany family (Meliaceae) which includes a large range of tropical trees and shrubs native to both the Old and New World. Evidence indicates that Neem might possess some hypoglycemic activity.

Panax Ginseng (Asian Ginseng):

There is some evidence that taking Panax ginseng orally, 200 mg daily can decline fasting blood glucose levels and hemoglobin A1c (HbA1c) in patients with kind II diabetes.

Prickly Pear Cactus (Nopal):

There is some preliminary clinical evidence that prickly pear cactus used orally can decline blood glucose levels in patients with kind II diabetes. Single doses can decline blood glucose levels by 17% to 46% in some patients. However, it is not known if extended daily use can consistently lower blood glucose levels and decline HbA1c levels. Only the broiled stems of the specific species Opuntia streptacantha seem to be advantageous and raw or crude stems do not seem to decline glucose levels. Other prickly pear cactus species do not seem to considerably lower blood glucose levels.

Red Sandalwood (Pterocarpus marsupium):

Like Gymnema Sylvestre, this is a traditional herb used in India to help rejuvenate the insulin-producing pancreatic beta cells. One group of researchers investigating diabetic rats compared Pterocarpus’ observed effects on blood glucose levels to those of metformin, a drug familiar to many diabetics.

Stevia (Sweet Herb):

Stevia is a non-caloric herb, native to Paraguay, which has been used as a sweetener and flavor enhancer for centuries. Clinical research indicates that stevioside, a component of Stevia, might reduce postprandial glucose levels by 18% in people with kind II diabetes.


Turmeric has been used for thousands of years in Asian Indian cookery and is an ingredient in curry powder. Ground from dried curcumin, a rhizome of the ginger family, turmeric is not peppery and rather mild tasting.

May decline blood sugar levels (and cholesterol). The apparent blocking of enzymes that transform dietary carbohydrates into glucose may be involved in this lowing of blood sugar.
