Health Benefits of Daily Consumption

The practice of eating ponnanganni keerai regularly is supported by its numerous health-promoting properties.

Enhanced Eye Health

Daily consumption is traditionally believed to improve and maintain vision. It is particularly rich in vitamin A and beta-carotenoids, which are crucial for preventing night blindness and protecting against dryness of the eyes. For centuries, it has been a go-to remedy in Siddha medicine for eye-related ailments.

Liver and Digestive Support

Ponnanganni keerai is known for its liver-protective qualities and is believed to aid in detoxification. It is used to improve bile flow and supports overall liver function. The fiber content helps regulate bowel movements, making it an excellent addition for digestive health and in preventing issues like piles.

Anti-inflammatory and Cooling Properties

According to Ayurveda, ponnanganni keerai has a cooling effect on the body, making it beneficial for balancing excess heat or Pitta dosha. Its anti-inflammatory properties can help with various conditions, from soothing gastric irritation to relieving nerve-related inflammation.

Potential Risks and Precautions for Daily Intake

While largely safe and beneficial, consuming ponnanganni keerai daily requires a few precautions. The primary concern is its oxalate content.

Oxalates and Kidney Health

Ponnanganni keerai, like many leafy greens, contains naturally occurring oxalates. In high concentrations, oxalates can bind with calcium, potentially contributing to kidney stones in predisposed individuals. However, cooking significantly reduces the oxalate levels, making the vegetable safer for regular consumption. People with a history of kidney stones or kidney disease should consult a doctor before making it a daily habit.

Digestive Concerns

In some cases, excessive daily intake might lead to mild diarrhea. It is advisable to consume it in moderation as part of a balanced diet rather than in extremely large quantities.
