In most cases, dried thyme is most effective if it is used during the early stages of cooking, just like bay leaves. This gives it time to infuse its flavor to the whole dish making your dish flavorful. Also, getting all the vitamins your body needs every day can be challenging. Luckily, thyme is packed with vitamin C and is also a good source of vitamin A. If you feel a cold coming on, thyme can help get you back in good health.
