Andrew Grace spoke with Caryn about the vegan diet he adheres to. He eats food and also chooses herbs and spices for cooking a completely wheat-free vegan cuisine based on the Chinese Traditional Medicine method of "temperature quality." Temperature quality divides food, herbs and spices as well as normal human past times like exercise or music appreciation into three basic qualities: Yang: Hot/Warm (as with garlic, onion, ginger, hard rock music, boxing, action films etc.), Neutral: (As with pinto beans, parsley, slippery elm, educational films, walking, elevator music), and Yin: Cool/Cold (As with watermelon, elder berry, classical piano music, yoga, Dramatic films). Andrew spoke about how what we need is based on pulse and tongue color. In general one who has a strong pulse and a red tongue usually needs neutral and Yin. People with white tongues and light pulses need neutral and Yang and normal people, as is for all people, with normal pulse and normal tongue need only neutral. It is believed that with the correct temperature quality food, past times and herbalogy, wellness is obtained and disease can be avoided or cured.
