Rachael Ray S14E28 - Dr. Roshini Raj is opening our 'Medical Mailbag'

We've got a doctor in the house today: Dr. Roshini Raj is opening our "Medical Mailbag" and answering viewers' questions about their health. How does hyaluronic acid actually work? Why do you get headaches when the seasons change? She has these answers and more. Then, "Party of Five's" Scott Wolf is chatting with Rach about playing the dad to Nancy Drew in the all-new television reboot. Later, Rach is making Eggplant Parm Steaks with Tomato Sauce Pesto (another recipe from her new book!) for dinner.
