A Traditional Japanese Herb with Modern Appeal
Ashitaba, or Angelica keiskei, is a large, leafy green herb native to Japan's Izu Islands, where locals have long consumed it for its reputed longevity-promoting qualities. The plant's most notable characteristic is its ability to quickly regenerate its foliage overnight after being cut, giving rise to its name "tomorrow's leaf". The healing power of Ashitaba lies in its rich composition of bioactive compounds, particularly unique flavonoids called chalcones, such as xanthoangelol and 4-hydroxyderricin, which are responsible for its potent medicinal effects.
The Power of Chalcones: Antioxidant and Anti-Inflammatory Action
One of the most well-documented health benefits of Ashitaba is its powerful antioxidant and anti-inflammatory activity. The chalcones in the yellow sap of the plant are strong antioxidants that scavenge free radicals, protecting cells from damage and preventing oxidative stress. This cellular protection is crucial for preventing chronic diseases and slowing the aging process.
Targeting Inflammation at the Source
Ashitaba's anti-inflammatory effects are equally significant. Studies have shown that its chalcones can inhibit inflammatory pathways, such as those involving protein tyrosine phosphatase 1B (PTP1B). This can help manage conditions linked to chronic inflammation throughout the body, from the cardiovascular system to the joints and skin.
Metabolic and Cardiovascular Support
For those concerned with metabolic health, Ashitaba offers promising benefits. Research suggests it can help manage weight and blood sugar levels. Studies on diabetic mice have shown that Ashitaba chalcones can help the body better process sugar by improving glucose uptake in muscles and reducing high blood sugar.
Aiding Weight Management
Ashitaba's potential for weight management comes from its ability to support metabolic function. The chalcones may block fat cell formation and improve insulin sensitivity. In one double-blind study involving moderately obese adults, daily consumption of Ashitaba chalcone powder for eight weeks led to a significant reduction in body weight and visceral (belly) fat.
Promoting Heart Health
Beyond weight, Ashitaba supports cardiovascular wellness. Its antihypertensive properties may work by inhibiting ACE, an enzyme involved in narrowing blood vessels, which helps control blood pressure. Ashitaba also contains compounds that help prevent blood clots and lower cholesterol levels, reducing the risk of heart attack and stroke.
Neurological and Digestive Health
Ashitaba's benefits extend to the nervous and digestive systems. Unique to Ashitaba, its chalcones have been found to stimulate the production of Nerve Growth Factor (NGF). NGF is a vital protein that helps protect and maintain neurons, showing potential in alleviating symptoms of certain neurological disorders. Additionally, Ashitaba contains compounds that can boost brain-derived neurotrophic factor (BDNF), which is crucial for cognitive function, memory, and higher thinking.
For digestive health, the fiber content in Ashitaba is beneficial for the gut. Traditional medicine on Hachijo Island refers to Ashitaba as a "stomach medicine" for its ability to aid digestion, relieve constipation, and combat harmful bacteria and toxins in the digestive tract. It may also help reduce gastric secretions, potentially protecting against stomach ulcers.
Skin and Immune System Support
Ashitaba's potent antioxidant and anti-inflammatory properties are also harnessed in skincare applications. Its compounds are believed to promote cellular renewal, helping to slow the aging of skin cells by stimulating a cellular recycling process called autophagy. This helps to reduce hyperpigmentation and combat premature skin aging. Ashitaba is rich in vitamins A, C, and E, which support immunity and skin health.
