The Antioxidant Power of Basil Extracts and Their Role in Disease Prevention
Blog Article
Basil is an herb that is closely related to mint. It has been used for thousands of years as both a culinary seasoning and a medicinal herb. There are over 150 varieties of basil but the most common types used both in cooking and herbal medicine are sweet basil and holy basil. The major active compounds in basil are volatile oils like linalool and eugenol which give it a pleasant aroma and flavor.
Antioxidant Power of Basil Extracts
One of the major health benefits of Basil Extracts comes from its impressive antioxidant levels. It is high in polyphenolic compounds like flavonoids which have potent free radical scavenging abilities. Laboratory studies have shown basil extracts to have an oxygen radical absorbance capacity (ORAC) score on par with blueberries and cranberries. Consuming foods and herbs high in antioxidants is important for reducing oxidative stress in the body. Oxidative stress has been linked to accelerated aging and many chronic diseases.
The antioxidants in basil may help protect cells from damage. Some research indicates basil extract supplementation can lower biomarkers of oxidative stress like malondialdehyde levels. Antioxidants from basil are thought to aid heart health by reducing LDL cholesterol oxidation, lowering blood pressure, and preventing platelet aggregation. They may also support brain function by neutralizing free radicals implicated in neurodegenerative conditions. The antioxidants in basil extracts provide diverse whole-body protection against oxidative stressors.
Anti-Inflammatory Properties of Holy Basil
One variety with especially impressive medicinal properties is holy basil, also known as tulsi. It has a long history of traditional use in Ayurvedic medicine to treat colds, flu, fever, inflammation, and respiratory issues. Modern science supports some of these usages, finding holy basil to have anti-inflammatory, antiviral, and bronchodilatory effects.
Lab and animal research shows holy basil reduces expression of pro-inflammatory markers like TNF-alpha, IL-1beta, and IL-6. It also blocks production of inflammatory prostaglandins and leukotrienes via inhibition of COX-2 and 5-LOX enzymes. These anti-inflammatory actions are partly due to ursolic acid and rosmarinic acid compounds found abundantly in holy basil. Studies suggest it may help ease inflammatory conditions such as arthritis as well as respiratory issues like asthma when taken regularly. The anti-inflammatory properties of holy basil make it useful both for preventing chronic disease and easing acute symptoms.
Antimicrobial Activity of Sweet Basil
Sweet basil is another variety with noteworthy disease-fighting qualities. Its volatile oils give it potent antimicrobial properties effective against harmful pathogens. Tested against common bacteria, molds, and yeasts, sweet basil extract showed activity against Staphylococcus aureus, E. coli, Candida albicans, and others. Additionally, it may help defend against antibiotic resistant "superbugs" like methicillin-resistant S. aureus (MRSA).
Basil's bacterial-fighting effects appear to work via disruption of cellular membranes in microbes. Being an anti-septic, it may help destroy odors and promote wound healing when applied topically as well. As an infusion, basil can make a supportive treatment for minor skin infections. Its antifungal abilities suggests use against fungal infections of skin, hair, and nails too. Adding basil extract to personal care products or using it as a natural mouth rinse adds antimicrobial protection. Overall, sweet basil demonstrates usefulness in maintaining whole-body microbial balance.
Possible Benefits for Metabolic Health
Basil may be able to aid metabolic wellness through antioxidant and anti-inflammatory activities supporting overall cellular functioning. Animal studies show basil improves liver and kidney biomarkers, regulates blood lipids, and enhances insulin sensitivity. Some evidence also links it to healthy blood pressure control. These metabolic effects could arise from basil's high levels of phenolic acids and polyphenols like rosmarinic acid which may activate antioxidant signaling pathways.
More research is still needed. But preliminary findings suggest basil extract intake supports healthy metabolic functioning and weight maintenance in part by reducing oxidative stress and mild inflammation throughout the body. Its polyphenols appear to benefit cells in the liver, pancreas, fatty tissue and more by enhancing cellular communication. More human trials are still needed, yet early signs hint that incorporating basil into the diet may help optimize metabolic processes and reduce disease risk factors over the long term.
Potential Cognitive Enhancing Effects
The antioxidant properties of basil may confer brain-health benefits as well. Oxidative stress and inflammation are involved in neurological conditions like dementia. Studies show rats given basil extract exhibit improvements in memory and cognition on maze tests. This effect appears related to basil's ability to reduce brain lipid peroxidation and levels of acetylcholinesterase, an enzyme implicated in Alzheimer's disease progression.
Certain basil compounds like rosmarinic acid seem to cross the blood-brain barrier and act as neuromodulators. They may protect neurons from glutamate-induced excitotoxicity as well as shield against amyloid beta plaque formation. While needing human verification, these findings suggest regular basil consumption could support brain function and guard against age-related cognitive decline when combined with a healthy lifestyle. Due to its antioxidant-rich profile, basil extracts may prove useful as a natural cognitive enhancer and dementia preventative.
Potential Role in Cancer Prevention
Ongoing research explores basil's potential anticancer actions. Test tube and animal studies indicate basil extract can inhibit tumor growth and cancer cell proliferation.
