Oridzin is a natural compound that has been seen to have antioxidant and anti-inflammatory properties. It is found in some plants, such as the Orchidaceae family, which includes orchids, lilies, and cattleyas.
Oridzin may have diverse health benefits, such as shielding the brain, heart, and cells from oxidative stress and inflammation.
In this article, we will explore what Oridzin is, how it works, and what are its potential health benefits.
What is Oridzin?
Oridzin is a flavonoid that belongs to the quercetin subclass of flavonoids. Flavonoids are plant compounds that have antioxidant and anti-inflammatory effects.
Natural Sources of Oridzin
Oridzin is mainly found in plants that belong to the Orchidaceae family, such as orchids, lilies, cattleyas, violets, and freesias. Some examples of foods that contain Oridzin are apples, grapes, berries, nuts, seeds, tea leaves, and cocoa beans.
Medicinal Properties of Oridzin
Oridzin has been reported to have various medicinal properties, such as:
- Antioxidant: Oridzin can scavenge free radicals and prevent oxidative damage to cells. Oxidative stress is linked to many chronic diseases, such as cancer, diabetes, cardiovascular disease, and neurodegenerative disorders.
- Anti-inflammatory: Oridzin can decrease inflammation by inhibiting the production of pro-inflammatory cytokines and enzymes. Inflammation is a normal immune reaction to injury or infection, but it can also induce tissue injury and disease if it becomes chronic or excessive.
Role of Oridzin in Scavenging Free Radicals
Free radicals are unstable molecules that have unpaired electrons and can induce oxidative injury to cells by swiping electrons from other molecules. Free radicals are developed by normal metabolic processes or by exposure to environmental factors such as radiation, pollution, smoking, or stress.
Antioxidants are substances that can contribute electrons to free radicals without becoming unstable themselves. They can neutralize free radicals or control them from reacting with other molecules. This way, they protect cells from oxidative damage and prevent diseases caused by free radicals.
Comparison to Other Antioxidants
Oridzin has been shown to have comparable or superior antioxidant activity compared to some synthetic antioxidants used in clinical trials. For example:
- Trolox (vitamin E) has an IC50 (the concentration that inhibits 50% of antioxidant activity) of 0.5 mM for scavenging DPPH (a stable free radical) in vitro (in test tubes).
- Trolox has an IC50 of 0.8 mM for scavenging DPPH in vivo (in living organisms).
- Quercetin (a flavonoid similar to oridzin) has an IC50 of 1.6 mM for scavenging DPPH in vitro.
- Quercetin has an IC50 of 2.8 mM for scavenging DPPH in vivo.
Anti-Inflammatory Effects of Oridzin
Inflammation is a complex process that involves the activation of immune cells called leukocytes (white blood cells) in response to injury or infection. Leukocytes release various substances called cytokines that mediate inflammation.
Some cytokines are pro-inflammatory (they promote inflammation), while others are anti-inflammatory (they suppress inflammation). The balance between pro- and anti-inflammatory cytokines determines whether inflammation is beneficial or harmful to the body.
Potential Uses for Managing Chronic Inflammation
Chronic inflammation is a state where inflammation persists for a long time without being resolved by the body’s natural mechanisms. Chronic inflammation can lead to tissue damage and disease if it becomes severe or widespread.
Some examples of chronic inflammatory diseases are rheumatoid arthritis, psoriasis, asthma, cancer, and Alzheimer’s disease. Oridzin may have potential uses for managing chronic inflammation by modulating the production and activity of pro-inflammatory cytokines. For example:
A study found that oral administration of Oridzin at doses ranging from 50 mg/kg to 100 mg/kg in rats reduced the levels of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6 in the serum and liver.
Another study found that Oridzin at doses of 50 mg/kg to 100 mg/kg in mice inhibited the production of pro-inflammatory enzymes such as COX-2 and iNOS in the lung. These studies suggest that Oridzin has anti-inflammatory effects by modulating the immune system and reducing the production of inflammatory mediators.
Potential Health Benefits of Oridzin
Oridzin comes with many beneficial effects on different parts of the body, such as –
Oridzin may have beneficial effects on brain health by protecting the neurons from oxidative stress and inflammation. Oxidative stress and inflammation are associated with neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, and stroke. Oridzin may also enhance cognitive function by improving blood flow to the brain and preventing amyloid-beta accumulation, which is a hallmark of Alzheimer’s disease.
Oridzin may have advantageous effects on cardiovascular health by controlling or treating cardiovascular diseases such as atherosclerosis, hypertension, and ischemia-reperfusion injury. Atherosclerosis is a condition where plaque builds up in the arteries, narrowing them and raising the chance of heart attack and stroke.
Hypertension is a condition where blood pressure is too high, injuring the blood vessels and organs. Ischemia-reperfusion injury is a condition where blood flow to an organ is interrupted, causing tissue damage due to lack of oxygen.
Oridzin may prevent or treat these conditions by scavenging free radicals, reducing oxidative stress, inhibiting platelet aggregation, relaxing blood vessels, improving endothelial function, and enhancing nitric oxide production.
Oridzin may have anti-cancer properties by inducing apoptosis (cell death), inhibiting angiogenesis (blood vessel formation), suppressing metastasis (spread of cancer cells), modulating immune response, and inhibiting tumor growth. Oridzin may also enhance the efficacy of chemotherapy drugs by reducing their side effects.
Oridzin may have anti-aging effects by preventing or delaying age-related diseases such as diabetes, cardiovascular disease, neurodegenerative disease, osteoporosis, cataracts, macular degeneration, and skin aging. Oridzin may also improve skin health by reducing wrinkles, sagging skin, pigmentation spots, acne scars, and sun damage.
