Ginger Root Extract

For many years the routine medical approach in treating peptic ulcers has been to reduce gastric acidity with antacids or strong drugs which block stomach acid secretion. Two of the world’s best-selling medications for this are Zantac and Tagamet. They are now available in OTC (over-the-counter) versions at somewhat weaker strengths. In prescription form, however, they are much stronger but also more expensive: Zantac at $48.00 for 30 tablets, and Tagamet at $29.00 for 30 tablets. A relatively new third anti-ulcer medication that made its debut in late 1995 is called Prilosec. It is extremely potent and terribly expensive at $104.00 for 30 tablets or a month’s supply.

While they do work for the purpose they’re chiefly intended, namely to halt stomach acid production and thereby give relief to ulcers, all three have some nasty side effects if taken for very long. The number involved reads like a bad laundry list of health dilemmas: nausea, vomiting, constipation, diarrhea, some vitamin and mineral deficiencies, liver damage, hair loss, male breast enlargement, dizziness, allergies, headaches, osteoporosis, depression, insomnia, and impotence.

This is why it is much better to use something natural — an agent that is simple but safe and effective, and inexpensive. The compound referred to is DGL or Deglycyrrhizinated Licorice. The glycyrrhizinic acid component of the root has been removed since it can aggravate hypertension, irritate the kidneys, and induce gout if accumulated in the body for very long. DGL is the preferred form of licorice throughout Europe, much of Asia, and India. But, oddly enough, it is hardly used by herb companies in North America.

A 1982 clinical study tested Tagamet (1 gram daily) and DGL (in the form of Caved-S at six tablets daily) for up to 12 weeks on 100 patients suffering from gastric ulcers. Doctors confirmed that the DGL preparation was “as effective as cimetidine [Tagamet] in gastric ulcer therapy.”

But what would happen if DGL were tested against Zantac and Tagamet? In several head-to-head comparison studies, it was amply demonstrated that DGL was more effective than either Zantac or Tagamet in both short term treatment and maintenance therapy of peptic ulcers. Furthermore, DGL yielded none of the untoward side-effects that the other two drugs did, and did the job of ulcer healing at just a fraction of the cost.

Ulcer sufferers can obtain outstanding help at a fabulous price: two 380 mg chewable tablets of DGL 20 minutes before a meal at less than $25.00 per month! Now that’s a savings worth considering, not only for your pocket book but also for your body as well.

Ginger is a well known spice and flavoring agent which has also been used in traditional medicine in many countries. This large seasonal plant is cultivated in Southeast Asia and China, India, and some parts of Africa. Ginger and turmeric plants have several similar characteristics – both possess pale green flowers and are surrounded by long lanceolate leaves.

Ginger, a source of valuable phytonutrients, is characterized as having an aromatic odor and a pungent taste¹. The part of the ginger plant that is used is the root, which is botanically the rhizome. The flat surfaces of the rhizome are removed, leaving the remains of the underground stem². Ginger contains essential oils including gingerol and zingiberene. It also contains pungent principles such as zingerone, gingerol and shogaol³.

For centuries, in Ayurvedic and Tibetan systems of medicine, ginger has been used in the management of headache, nervous diseases, nausea, and vomiting. Ginger has been noted to treat migraine headaches without side-effects⁴. In addition, it is also recommended in the management of rheumatic disorders and muscular pain⁵.

Chemistry

The ginger rhizome has the following chemical composition:

• 60% starch,
• 10% proteins,
• 10% fats,
• 5% fibers,
• 6% inorganic material,
• 10% residual moisture,
• 1-4% essential oil⁵.

The percentage of essential oil varies with geographic origin. However, its chief elements, sesquiterpene hydrocarbons, remain constant. These include (-)-zingiberene, (+)-ar-curcumene, (-)-ß-sesquiphellandrene, E, E- a -farnesene, and b -bisabolene. These essential oils occur alongside monoterpene alcohols and aldehydes present as glycosides. A mixture of many terpenes and some non-terpenoid compounds make up the essential oil.¹ It has been speculated that since there are a variety of chemical classes that these compounds can belong to, it is likely that ginger can eliminate symptoms associated with a variety of illnesses, such as arthritis, by interfering with the production and release of metabolic products from lipid membranes, peptides, proteins and amino acids.

Experimental data reveal that ginger may be a dual inhibitor of eicosanoid synthesis, inhibiting the synthesis of both prostaglandins and leukotrienes, which are inflammatory mediators produced from arachidonic acid⁵.

The rhizome contains a variety of chemicals called gingerols which provide its distinctive taste and characteristic pharmacological effects. The chemical constituents responsible for the pungent taste of ginger are 1-(3’ –methoxy –4’-hydroxypheny1)-5-hydroxyalkan- 3-ones, also known as [3-6]-,[8]-,[10]-,and [12]-gingerols.¹

Biological Effects and Clinical Uses

In recent years, researchers have scientifically validated many of the therapeutic uses of ginger.

• • One study indicates that ginger is effective in reducing inflammation in arthritic conditions. In a study conducted with 56 patients experiencing either rheumatoid arthritis, osteoarthritis, or muscular discomfort, 75% experienced relief in pain and swelling after using powdered ginger. Furthermore, none of the patients complained of any side effects while using ginger to treat their symptoms. It is suggested that ginger works as an inhibitor of prostaglandin and leukotriene biosynthesis to produce its ameliorative effects.⁵

• • Another case study presented ginger as a preventive agent for migraine headache. In this application, one subject was given non-steroidal antiinflammatory medication to permit her migraine headaches to subside. However, even though her headache was eliminated in time, other side effects including depression and redness of the eyes appeared. The subject was then given ginger. With 500-600 mg of powdered ginger mixed with water, the migraine headaches ceased within 30 minutes. In addition, after the cessation of the migraine attack, the subject did not experience any side effects. Migraine headaches are an accumulation of pain syndromes.

Many anitihistamines are used to treat migraines. Ginger has been shown to contain antihistamine and antioxidant factors as well as possess anti-inflammatory action⁴.

• • The effect of ginger on stimulation of bile secretion was studied to identify the basis of its action as a metabolism enhancer. Results of this specific study reported that the acetone extracts of ginger, comprised of the essential oils and the pungent principles, produce an increase in bile secretion. The two pungent principles that were chiefly accountable for the cholagogic effect of ginger include [6]-gingerol and [10]-gingerol. Bile acids facilitate absorption of fat and electrolytes and peristalsis of the small intestine. Since ginger has been reported to increase bile secretion, it may be beneficial in the excretion of gallstones.³

• • Furthermore, a study was done on 20 healthy male individuals that were given 50 g of butter and 5g of ginger a day for seven days. Addition of five grams of ginger with a fatty meal inhibited the platelet aggregation induced by adenosine diphosphate and epinephrine to a large extent. Ginger has been reported to inhibit prostaglandin synthesis in It has been reported that dietary fat content affects platelet aggregation by modifying prostaglandin metabolism. Inhibiting the transformation of arachidonic acid to thromboxane and decreasing the sensitivity of platelets to many aggregating agents may be possible with the administration of ginger in a fatty diet.⁶

• • In view of the fact that ginger root has been used in several parts of the world in the management of motion sickness, researchers attempted to elucidate the mechanism of action. In one of the earlier studies, it was proposed that ginger constituents may increase gastric motility and prevent the accumulation of toxic substances, thereby blocking the gastrointestinal reactions which trigger the nausea feedback⁸. A more recent study addressed the role of ginger in preventing the nausea feedback at the nerve receptor level. In motion sickness, nausea and vomiting are mediated by specific receptors in the central and peripheral nervous system. These receptors are activated by the chemical messengers, acetylcholine and histamine. Ginger produces antimotion sickness action probably through anticholinergic and antihistaminic effects⁹.

The above studies indicate the inhibitory effects of ginger on synthesis of inflammatory mediators and the beneficial effects of powdered ginger as well as the isolated gingerols on digestion and metabolism. In view of these effects, ginger is a potential herbal alternative in the management of digestive disorders, migraine, painful arthritic conditions and motion sickness. The herb may be potentially useful in improving blood circulation as well, on account of its inhibitory effects on platelet aggregation. When used as a spice or therapeutically at the recommended levels, [for motion sickness: 300 mg of the extract (containing 5% gingerols) daily in divided doses; for digestive distress: (75 mg of the extract daily in divided doses)], ginger does not have any reported side effects⁷.
