Aojiru Health Benefits

Aojiru Health Benefits

What is barley grass?

Barley grass refers to the young shoots of the barley plant, specifically the leaves, and stems before the plant reaches maturity. This drink is typically made from the juice of these young barley grass. The drink’s green color comes from the chlorophyll present in these fresh green barley leaves. These leaves are often juiced or powdered to make the Aojiru drink. 

Barley (Hordeum vulgare), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains; it was domesticated in the Fertile Crescent around 9000 BC, giving it nonshattering spikelets and making it much easier to harvest. Its use then spread throughout Eurasia by 2000 BC. Barley prefers relatively low temperatures to grow, and well-drained soil. It is relatively tolerant of drought and soil salinity, but is less winter-hardy than wheat or rye.

Taxonomy of Barley

Before discussing Aojiru’s health benefits, consider and understand the source used in the drink. 

Barley (Hordeum vulgare) is a cereal grain belonging to the Poaceae grass family. Its taxonomy is as follows:

  • Kingdom: Plantae
  • Phylum: Angiosperms
  • Class: Monocots
  • Order: Poales
  • Family: Poaceae
  • Genus: Hordeum
  • Species: Hordeum vulgare

The plant is an annual grass with erect stems, linear leaves, and flowers borne in dense spikes. Barley grains, used for food or animal feed, are rich in carbohydrates, proteins, vitamins, and minerals.

Is there any nutritional difference between Barley grass and barley matured grains?

Both young barley plants (barley grass) and barley grains contain beneficial compounds.

There are differences in their composition due to their developmental stages. 

Barley Grass

Barley grass, harvested early on, is rich in chlorophyll, vitamins, minerals, antioxidants like flavonoids and phenolic compounds, enzymes, and amino acids. These nutrients are often found in higher concentrations in young shoots than mature grains.

Barley Matured Grains

Barley grains, on the other hand, are a source of fiber, carbohydrates (including both simple and complex carbohydrates), some proteins, B vitamins (like niacin, thiamine, and folate), and minerals (such as selenium, zinc, and magnesium). 

So, barley grass and barley grains offer nutritional benefits, but their concentrations of specific bioactive compounds differ due to their growth stages. However, Aojiru’s health benefits can only be found in barley grass.

Aojiru Health Benefits

The health benefits of Aojiru are derived from its bioactive compounds that enhance bodily organ functions. These compounds notably improve various physical systems, highlighting the positive effects of Aojiru on health, as outlined below:

Liver Support

The chlorophyll in Aojiru aids the liver by enhancing its detoxification processes. It assists in flushing out toxins and heavy metals from the body, reducing the burden on the liver. Additionally, Aojiru’s antioxidants, including vitamins C and E, protect liver cells from oxidative damage caused by free radicals, promoting liver health and function.

Digestive System Enhancement

Enzymes in Aojiru, like amylase and lipase, aid in the breakdown of carbohydrates and fats, respectively, facilitating smoother digestion. Its high fiber content promotes gastrointestinal health by supporting regular bowel movements and fostering a diverse and healthy gut microbiome, essential for overall digestive well-being and nutrient absorption.

Skin Nourishment

Aojiru’s antioxidants, such as beta-carotene, vitamin E, and flavonoids, shield the skin from oxidative stress and damage caused by free radicals. These compounds also promote collagen synthesis, improving skin elasticity and reducing the appearance of wrinkles. Chlorophyll’s anti-inflammatory properties may aid in calming skin irritations and supporting wound healing.

Immune System Boost

Its nutrient profile, vitamins C and E, and minerals like iron, zinc, and selenium fortify the immune system. Vitamin C stimulates the production of white blood cells, crucial defenders against infections. The iron and zinc play pivotal roles in immune cell function and response, collectively supporting a robust immune system.

Heart Health

Potassium, flavonoids, and polyphenols found in Aojiru contribute to heart health by regulating blood pressure, reducing the risk of hypertension, and protecting against oxidative damage to blood vessels. These compounds support cardiovascular function and reduce the risk of heart disease.

Kidney Wellness

By aiding detoxification, Aojiru helps alleviate stress on the kidneys. This may assist in reducing the risk of kidney-related issues and support overall kidney health by ensuring proper elimination of waste and toxins from the body.

Eye Protection

Lutein, zeaxanthin, and beta-carotene present in Aojiru accumulate in the retina. They protect against oxidative stress and potentially reduce the risk of age-related macular degeneration and cataracts. These compounds promote optimal eye health and vision.

Cognitive Function

Antioxidants in Aojiru, like vitamins E, C, and beta-carotene, support cognitive function by protecting brain cells from oxidative damage and inflammation. These compounds reduce the risk of cognitive decline and support overall brain health.

Bone Strength

Calcium, magnesium, and vitamin K content in Aojiru are critical in maintaining bone health. Calcium and magnesium contribute to bone density and strength, while vitamin K aids in bone mineralization. Collectively, they reduce the risk of osteoporosis and fractures.

Blood Health

Chlorophyll in Aojiru, with its similar structure to hemoglobin, potentially aids in red blood cell production, supporting better oxygen transportation and enhancing overall blood circulation.

Weight Management

Its low-calorie, nutrient-dense nature supports weight management by providing essential nutrients without contributing to excessive calorie intake. Additionally, its fiber content promotes satiety, reducing overall calorie consumption and aiding in weight control. Reference.

Anti-inflammatory Effects

Aojiru’s diverse array of antioxidants, including flavonoids, polyphenols, and other phytochemicals, counteract inflammation by neutralizing free radicals and reducing the production of inflammatory compounds.

Energy Boost 

B vitamins, especially B6 and B12, found in Aojiru, participate in energy metabolism, converting food into energy and supporting mitochondrial function. This helps increase energy levels and combat fatigue.

Hormonal Balance

Phytoestrogens present in Aojiru help maintain hormonal balance, potentially reducing the risk of hormone-related issues and supporting overall hormonal health in both men and women.

Cellular Health

The rich antioxidant profile of Aojiru shields cells from damage caused by free radicals. It promotes cellular health and potentially reduces the risk of various diseases associated with oxidative stress.


By supporting multiple organs and bodily systems, Aojiru contributes to overall health improvement.

 Incorporating Aojiru into one’s daily routine offers comprehensive health benefits, including supporting various bodily functions and contributing to overall well-being. Aojiru’s health benefits encompass improved digestion, boosted immunity, detoxification, and increased energy levels, making it a valuable addition to a healthy lifestyle.
