One of the most renowned benefits of Manathakkali keerai is its ability to soothe and heal mouth and stomach ulcers. Traditional preparation methods involve chewing the raw leaves or preparing a simple soup (thanni saaru) to provide rapid relief from the pain and discomfort of ulcers.

Manathakkali keerai is rich in antioxidants, which combat free radicals that cause cellular damage and contribute to premature ageing. The presence of active compounds like alkaloids and flavonoids gives it potent anti-inflammatory effects. This makes it beneficial for relieving joint pain, arthritis, and other inflammatory conditions.
Supporting Liver Health
The plant has been traditionally used as a liver tonic. Its hepatoprotective properties help detoxify the liver and protect it from damage. Some studies have even explored its potential in treating liver-related conditions, including hepatitis C and liver cirrhosis, due to its antiviral and antioxidant content.
Promoting Digestive Wellness
The fibre content in Manathakkali keerai aids in regular bowel movements, preventing constipation. It is also known to help with indigestion, stomach cramps, and appetite loss. For optimal results, it can be consumed as a soup or added to various dishes.
Enhancing Skin Health
For centuries, the keerai has been used topically to treat a variety of skin ailments. Its antibacterial and anti-inflammatory properties can help with skin infections, eczema, and rashes. A paste of the leaves can be applied to affected areas to soothe irritation and promote healing.
