Curcumin is a chemical that is an important component of the Indian spice turmeric. Both ginger and turmeric have a number of health benefits and are important cooking ingredients in the cuisine of many countries.
Whether it is better to use them in your cooking or drink them as a kind of tea, or even perhaps plain or in powdered form, depends on the purpose for which you are using them. If, for example, you are using ginger for a sore throat, then a tea is certainly much more effective. For a toothache, you need to chew a small piece of raw ginger. On the other hand, for a problem like flatulence, it is recommended that you add ginger to your food. Curcumin has many health benefits (such as prevention of cancer) that are best obtained when the substance is absorbed by the body, but using it to cook is as effective as drinking it as a tea. Even when turmeric and ginger are used in food, they are not simply added to a dish - the dish is actually cooked with these ingredients. Therefore whether you cook with them or drink them as a tea, your body will absorb them equally well.
