Fennel is a perennial, pleasant-smelling herb with yellow flowers. Its native is the Mediterranean but is now found throughout the world. Its flavor comes from anethole, an aromatic compound also found in anise and star anise, and its taste and aroma are similar to theirs, though usually not as strong.
Turmeric and especially its most active compound, curcumin have many scientifically proven health benefits, such as the potential to improve heart health and prevent Alzheimer's and cancer. It's a potent anti-inflammatory and antioxidant. It may also help improve symptoms of depression and arthritis.
