I could eat pesto on just about everything. As a spread on warm bread, sauce over meats, drizzled over salads and into soups, and on pasta. So some good news for all you pesto lovers because it is extremely healthy aiding in digestion and boosting the immune system. It is good for gout, muscular aches and pains, rheumatism, and your respiratory system. Some studies show that basil is a cancer preventative herb. It also helps people with diabetes because it can lower blood sugar levels and aid insulin release.
