Green Tea for ED

  • May 20, 2020
When talking about green tea as a treatment for ED, it’s not really about a tea bag immersed in a cup of hot water. Instead, we are referring to the supplements found and extracted from the green tea.

The green tea itself is obtained from the tea plant species known as Camellia sinensis, or, more commonly, the Chinese tea. Its bud and leaves are used to make green tea.

Originally produced in China, its production has grown and spread to several East Asian countries.

Green tea contains several components, and they all have different benefits. Not all are exclusively used for treating ED. They include:

  • Caffeine
  • Catechins
  • Vitamins (C, B2, folic acid, β-carotene and E)
  • L-theanine
  • Fluorine
  • Saponins
  • Chlorophyll
  • GABA

Of all the components, the two most useful elements that are helpful in erectile function are catechins, specifically EGCG and L-theanine.

The catechins found in green tea are fifty times stronger than cocoa and a hundred times stronger than wine. They are basically the strongest naturally occurring antioxidants.

They include Flavonoids, Epicatechin gallate, Epigallocatechin gallate (EGCG), and Epicatechins


EGCG is an antioxidant as it protects the body from cell damage caused by free radicals. Free radicals are highly particles that could damage cells. EGCG is also known to reduce inflammation and stress.

Studies have shown that ECCG intake increases erectile function. Because ED can be due to oxidative stress in the body, EGCG is one of the most potent antioxidants that solve the problem.[1]

Oxidative stress is a condition that occurs when there is excess reactive oxygen production than the body can deal with.


It is an amino acid found almost exclusively in pekoe, oolong, and green. It’s most effective in cases where ED is caused by stress.

Its intake increases the brain’s production of alpha brain waves that have a calming effect. It also increases alertness and focus. It will make your moods better. This has been proven through several tests conducted on both men and rats.[2]

Matcha vs. Normal Green Tea

Popular in the Japanese tea ceremonies, it is ground into a fine powder, unlike regular green tea that’s made of leaf fragments. Once mixed hot water, it’s instantly ready for use – regular green tea would need two minutes in hot water.

It doesn’t need to be brewed or steeped at all, unlike regular green tea.

Because it’s ground into powder, none of its antioxidants and nutrients are lost. The other reason why Matcha tea is so potent is its preparation process. Tea leaves for Matcha green tea are cultivated differently from leaves for regular green tea.

Matcha tea bushes are grown under special cloths, protected from the sun. They’re then given special post-harvesting treatment give it maximum potency. Their unique taste comes from their lack of exposure to the sun.

Once harvested, the leaves are briefly subjected to steam treatment. This prevents fermentation. They are then dried and allowed to age in cold medicine. This enhances its taste further.

Its caffeine content is higher than in regular green tea. For example, in a single cup of 237 ml, prepared from four teaspoons of powder, the average caffeine content is 280 mg. A similar cup of coffee would have similar caffeine content.

Compare that to a standard green teacup of the same volume, which contains approximately 35 mg only.

Unlike coffee, matcha tea has the L-Theanine ingredient, an amino acid that increases dopamine and energy levels and boosts focus. Dopamine activates the brain region that aids the feeling of pleasure, makes sex more enjoyable, and increases attraction.

Additionally, it counters all the side effects of caffeine.

Due to the way it’s cultivated and processed, matcha green tea is more potent than regular green tea for dealing with ED.

It causes vasodilation, the relaxation of the walls of blood vessels. This, in turn, lowers blood pressure, increasing blood circulation and oxygen flow to all major organs, including the penis. Vasodilation helps the penis attain a fuller, harder, and longer-lasting erection.

Matcha tea is best taken half an hour before sex.


Consumption of two to three cups of coffee daily has shown reduced erectile dysfunction in several tests conducted. Men had approximately 42% fewer chances of reporting ED if they took two to three cups of coffee daily.

This trend remained unchanged among obese, overweight, and hypertensive. The results are different among those suffering from diabetes.

It is believed that caffeine triggers the relaxation of the muscles and arteries that line up the penis. This, in turn, increases the blood flow in the penis.

Even though both tea and coffee have caffeine, the concentration in coffee is higher because coffee is a more potent drink.


One of the contents of green tea, as listed above, is GABA, also known as γ-aminobutyric acid. It is known to have several effects, one of them being relaxation. Green tea high on GABA content, known as GABA tea, acts as a sedative, thankfully without the risk of addiction.

In regular green tea, its content is 400 mg per 100 g of green tea, but in GABA tea, the content is approximately fifty times more. Consuming GABA tea makes it easier to sleep, not have an erection.
