Travalera (Centaurea aspera L.) is a plant commonly known as "plant insulin" due to its beneficial properties for regulating blood sugar levels. Used in natural medicine, this plant has a tradition in the treatment of diabetes, acting as a hypoglycemic. Its use is simple; one prepares an infusion by boiling 1 tablespoon of the plant in a cup of water, letting it steep for a few minutes before straining. It is recommended to consume 2 to 3 cups daily, preferably before meals. The ingredients are limited to the travalera plant, ensuring a natural and effective preparation. It is important to mention that, while it has traditional use, one should consider consulting a healthcare professional before using it as treatment.
