CORN is known botanically as Zea mays. It belongs to the family of grasses which is scientifically called Gramiaeae. Corn silk, also classified as Zea mays, is the silky (hair-like) styles (10-20cm long) found between the ears and the husks of corn. When fresh, they are light green or yellow-brown in colour. They are usually harvested when the husks are fresh; and they are dried in a warm and airy room or in a drying shed. The drying process takes approximately 7-14 days. Dried corn silk resembles fine, dark, crinkled hair, and is used as herb and not as food.
Dried corn silk is cut and stored in an airtight container - preferably in a dark glass container. The medicinal values, (especially the diuretic properties) of the silk, like those of any other herbs, diminish after about two years of storage. Corn silk is effective either fresh or dried. However, when used fresh, it may act as a laxative. It is one of the safest herbs that can be used for children, pregnant women, nursing mothers, adult and the aged.
Constituents Of Corn Silk:
Laboratory analysis reveals that the main active constituents of corn silk are as follows: Maizemic acid, fixed oil, mucilage, sugars, resin, saponin, salicylic acid, oxalic acid, alkaloids, tartaric acids, flavonoids, anthocyanins, tannins, thymol, steroids, allantoin, etc. Miscellaneous constituents of corn silk include: Vitamins (B vitamins and PABA, panthothenic acid, thiamin, beta carotene, Vitamins C and K); it also contains high amounts of potassium, silicon (silica), calcium, magnesium, iron, phosphorus and zinc.
Therapeutic Actions Of Corn Silk:
Diuretic, demulcent, tonic, mild stimulant, anti-inflammatory, analgesic, lithotriptic, antiseptic and antimicrobial; and is a mild anodyne.
Method of Preparation / Dosages:
(i) Infusion (tea): 1 to 2 teaspoons of the dried herb is infused for up to 10-15 minutes in a teacup of boiling water. This could be taken warm or cold 3 -5 times daily, depending on the severity of the condition.
Alternatively:-30g of the herb is infused in a litre of boiling water, and a cup (200 ml) is taken three times a day.
(ii) Decoction: The silk from 3 ears of fresh corn could be boiled with 3 tea cups of water for 5 minutes; and half or one cup of the decoction could be taken at once for up to 3-4 times a day.
(iii) Tincture of Corn Silk: Corn silk is soaked in 130g or 500ml of alcohol as a standard herbal tincture.
(iv) Corn Silk Capsules: Dried corn silk is powdered and capsulated. 2 capsules are taken 3 times daily with plenty of water at meal times.
Corn silk has been proven to have a very high amount of potassium which makes it a very balanced herbal diuretic. It stimulates the renal epithelium cells to excrete and increase urine flow in cases of water retention. Because of its high potassium contents, it does not upset the body’s normal chemistry (i.e. electrolyte balance). Also, due to its saponins, allantoin and mucilage contents, corn silk exerts demulcent or soothing and healing effects on irritated tissues in the body.
Therapeutic Indications (Or Uses Of Corn Silk)Corn silk is given as an effective and balanced herbal diuretic for minimizing oedema (water retention) at the in the lower limbs as in pedal oedema in pregnant women, prior to the monthly menstruation as in premenstrual syndrome (PMS), dropsies due to heart disease, hypertension or the subpalpebral oedema (bag of water under the eyes).
Unsweetened corn silk infusion alone is an excellent remedy given to children with profuse albumin in urine due to nephrotic syndrome (Nephrosis).
Corn Silk is used as a soothing and relaxing herb to help calm and alleviate the irritation and inflammations in the kidneys, urinary tract, prostate and the urinary bladder, which often result in burning and painful urination. Therefore, corn silk is usually recommended in cases of nephritis (inflammation of the kidneys), cystitis, urethritis, prostatitis and bedwetting.
Corn silk clears toxins, catarrh, cataract deposits and reduces the formation of sediments in the kidneys and bladder. It is used for the treatment of renal calculi (kidney stones) and urinary bladder stones and gravel.
The stone-breaking (litholytic) property of “stone breaker” (Phyllanthus nuriri) is enhanced when it is combined with corn silk and given as infusion (tea). Also, taking a mixture of corn silk and Phyllanthus nuriri as tea regularly helps in the treatment and prevention of gallbladder stones, cholecystitis (inflammation of the gallbladder) and sclerosis of the liver. Corn silk is a gentle blood-purifying remedy and it helps in clearing excessive uric acids deposited in the joints and body tissues. It also exerts some analgesic and anodyne actions in the body and this makes it useful in the treatment of rheumatism and arthritis, gout and sciatica.
A regular intake of corn silk infusion is one of the cheapest ways of losing excess body weight (obesity). For this purpose, corn silk is more effective when it is taken in combination with other herbs like chickweed (Stellaria media). Studies have shown that taking an overnight cold infusion of corn silk exerts hypoglycemic (blood sugar-lowering) effect, especially in an overweight patient. Taking corn silk infusion or the tincture will help in “cheering up a depressed spirit” and calming a restless mind.
