Ayurveda, the ancient Indian system of medicine, offers several herbs known for their cooling properties, ideal for combating the summer heat. Here are three such herbs:

1. Aloe Vera: Aloe Vera is known for its cooling and soothing properties, making it excellent for sunburns and other skin irritations caused by excessive heat. In Ayurveda, aloe vera is also used internally to cool the body by adding it in a juice and alleviates conditions like acidity and inflammation.
2. Mint (Pudina): Mint is a refreshing herb which gives it its cooling sensation. It is commonly used in Ayurvedic remedies to alleviate heat-related issues like indigestion, headaches, and excessive sweating. Mint tea or mint-infused water is a popular summer drink in many cultures for its cooling effect.
3. Fennel: Fennel seeds have a cooling effect on the body and aid in digestion. They can be chewed after meals to freshen the breath and prevent indigestion, bloating, and gas, which are common during the summer months.

These herbs can be consumed in various forms such as teas, infusions, or incorporated into meals to help the body stay cool and balanced during the summer heat.
