"Natural or Chemical-free toor dal" refers to toor dal (also known as arhar dal or pigeon peas) that has been cultivated and processed without the use of synthetic pesticides, chemical fertilizers, or genetically modified organisms (GMOs). Essentially, it's a term often used interchangeably with organic toor dal.

* Unpolished: Chemical-free toor dal is often unpolished, meaning it hasn't undergone artificial polishing with water, oil, or other substances. This helps retain the natural outer layer of the pulse, which contains essential fiber, proteins, and micronutrients.

 * Better Taste and Aroma: Many consumers report that chemical-free or organic toor dal has a more authentic, richer taste and aroma compared to conventionally grown varieties.

In summary, "chemical-free toor dal" emphasizes its natural cultivation and processing, making it a healthier, more nutritious, and environmentally conscious choice.
