Corn, which is believed to be first grown by Aztecs and Mayans, can be prepared as a meal. But did you know that the thin thread-like strands that are pulled off from the husk of the corn can make a healthy tea?

In most cases, many people throw corn silk away because they do not know they can use it to make tea. Corn silk tea is not popular to many, and its benefits are also not well known to many.

However, this tea has been used by Native Americans since 5000 B.C as an herbal remedy for various diseases.

Modern research has shown that the Native Americans who used corn silk tea as an herbal remedy were right since this tea is rich in antioxidants, polyphenols, vitamins, and minerals.

Corn Silk Tea Health Benefits

Used by different races since ancient times for healing and medicinal needs, corn silk tea possess many health benefits. While a few of its benefits have been proven beyond doubt by scientific studies, research is still being done on many other benefits that corn silk tea may possess. Let’s look at the few scientifically-proven benefits of this healthy tea;

1. It Is a Diuretic

Even historically, corn silk was known to increase peeing rates among users. And although the mechanism of why and how it was able to induce this effect was not known, modern research done on rodents has shown that extract from corn silk inhibits chloride and sodium reabsorption, and also increases glomerular filtration rate (GFR).

The results of the study showed that extracts from corn silk has diuretic effects. Urine flow in the tested rodents showed a 135% increases compared to those that were not given the substance. (1)

Sodium and chloride are known to make the body hold more water, and thus by reducing their reabsorption, the rate of weight loss is accelerated.

Although this effect has not been clinically tested in humans, there is some truth in terming corn silk tea as a diuretic. By helping your body lose more water, corn silk tea can help reduce bloating of your belly as a result of water retention by the body.

2. It Can Lower Blood Pressure

For people suffering from high blood pressure, corn silk tea may offer a natural way of regulating it. A clinical study conducted on 40 individuals showed positive results in terms of lowering blood pressure. 20 people with hypertension issues and 20 who had no issues with blood pressure. The patients were administered extract of corn silk in varying doses.

At the end of the trial period, individuals with high blood issues were found to have decreased their blood pressure. Also, it was seen that the higher corn silk doses, the higher the decline rate of blood pressure.

Therefore, we can conclude that although corn silk tea cannot be used as a substitute for your blood pressure medications, people with hypertension can drink this tea to keep their blood pressure in check. (2)

3. It May Be Useful In Treating Urinary Tract Infections

Native Americans were reportedly using corn silk tea to treat bladder infections, but it was not scientifically proven whether or not this tea was effective at treating the infections.

However, recently, a pharmaceutical college in Dubai tested different extracts of corn silk against various types of bacteria, including Staphylococcus aureus, Bacillus cereus, and Salmonella typhi.

The study concluded that the extracts had antimicrobial properties that reduced the activities of microbial bacteria in the body. Since most of the urinary tract infections are caused by e-coli, which is one of the bacteria tested, we can say that this tea can help clear out urinary tract infections. (3)

In addition, since it is a diuretic, there is a reason to believe that it can help your infection clear out fast.

Another use of corn silk tea is in helping young children stop bedwetting. Many blogs and YouTube videos have recommended corn silk to parents whose kids are bedwetting at night. Although there are scientific studies on kids or adults, animal research showed that corn silk tea could increase urine production, and thus should not be taken at night. (4)

However, if taken earlier in the day, then we can theoretically say that it may lessen the amount of water in the body at the end of the day, and thus lower chances of bedwetting. However, it is not possible to say the time one should take this tea to prevent bedwetting.

4. Skin Lightening and Concealing Marks On the Skin

Powdered corn silk was used for makeup in the 1960s, but it did not last long because of the popularity of synthetic ingredients.

Today, many people are beginning to use corn silk powder on their face to brighten their skin and reduce redness, and there is scientific evidence to prove that this really works.

In a study done on 21 women for a period of 8 weeks in Korea whereby water-based corn silk extracts were applied on their faces. The concentration of the solution was 1.5%, and the changes seen after 8 weeks were noticeable. After 8 weeks, Korean scientists found out that corn silk had decreased production of melanin by 37.7%, and there were no signs of cell toxicity.

In conclusion, they said that corn silk might be used as a de-pigmenting solution for suppressing skin hyperpigmentation. In other words, corn silk was found to promote a healthy skin tone and even out pigmentation. (5)

5. Might Aid Weight loss

Weight problems have become a health menace that affects many people these days. And although weight problems are caused by several factors including genetics, a lot of people experience weight gain due to excess water retention in the body, as well as toxic build-up in the digestive system.

Considering that corn silk tea is a diuretic and thus can help you get rid of excess water, and also toxins from the body, we can say that this tea can help you shed weight caused by excess water in the body.

There are scientific studies done on corn silk tea and how it can help with weight loss.

One such study done by a Chinese pharmaceutical university and published in 2017 involved testing corn silk polysaccharides on rats with insulin resistance. It was found that this treatment significantly reduced weight loss, blood glucose, and insulin levels, and also improved glucose intolerance

Therefore, by taking one or two cups of corn silk tea every day, you can benefit greatly in terms of weight loss. However, it should not be used solely as a solution to weight problems. (6)

In another Chinese study whereby rodents with type 2 diabetes were administered flavonoids from corn silk, it was revealed that the corn silk flavonoids significantly reduced weight loss, water consumptions, and reduced blood glucose concentration in the body. (7)

Although these studies we have quoted here were not geared towards finding the effects of corn silk on weight loss, the results showed that it is effective at weight loss. Of course, there is a need for studies to be done on human beings, but it is promising.

6. It Can Help Manage Kidney Problems

Corn silk tea is a great remedy for kidney problems. This tea is helpful in treating conditions associated with kidney such as inflammation of the urinary system, kidney stones, bladder infection, prostate problems, etc.

In a study done by the South Korean university showed that corn silk tea could help reduce the growth of prostate cancer cells. However, this was just a lab study conducted using cultured cells. (8)

As discussed earlier, corn silk tea consumption can help improve urine flow and reduce possibilities of formation of sediments in the kidney, which can ultimately result in the formation of kidney stones. However, it is important to mention that consumption of this tea will not treat kidney stones- it only helps prevent the occurrence or worsening of this problem.
