Key Medicinal Benefits of Siru Keerai
Supporting Digestive Health
Siru Keerai's high fiber content acts as a natural laxative, promoting smooth and regular bowel movements. It is traditionally recommended for people with gastric issues and has been shown to help cure stomach and intestinal ulcers. The fiber also helps maintain a healthy gut microbiome, which is crucial for overall digestive wellness.
Combating Anemia and Boosting Blood Health
The high concentration of iron in Siru Keerai makes it a powerful remedy for iron-deficiency anemia. Regular consumption helps boost the body's iron levels and stimulate the production of red blood cells, which can alleviate symptoms like fatigue and weakness. It is often recommended for anemic patients and new mothers to help restore blood values after childbirth.
Promoting Strong Bones and Teeth
Siru Keerai is a rich source of calcium and phosphorus, two critical minerals for maintaining strong bones and teeth. The presence of Vitamin K, which is abundant in leafy greens, also plays a role in bone health by aiding in blood clotting and regulating bone mineralization.
Improving Eye Health
Rich in Vitamin A and carotenoids like beta-carotene, lutein, and zeaxanthin, Siru Keerai acts as a bodyguard for your eyes. These antioxidants protect the macula and retina from oxidative stress and sun damage, potentially lowering the risk of age-related eye disorders like macular degeneration and cataracts.
Cleansing the Kidneys and Urinary System
In traditional medicine, Siru Keerai is valued for its ability to address urinary problems. It is known to help in removing toxins from the kidneys and cleansing the urinary tract, potentially aiding in the treatment of kidney stones and other related issues.
Addressing Skin Ailments
Traditionally, preparations of Siru Keerai have been used to treat skin conditions. Its anti-inflammatory and antiseptic properties make it a beneficial topical and internal remedy for issues like scabies and eczema.
Antioxidant and Anti-inflammatory Properties
Research confirms that Siru Keerai possesses powerful antioxidant activity, which contributes significantly to its anti-inflammatory effects. The bioactive compounds help neutralize harmful free radicals, reducing inflammation throughout the body and protecting against chronic diseases.
