The invention discloses rice with spirulina and effects of clearing heat and lowering fire and a method for preparing the rice. The rice is made of, by weight, 30-45 parts of spirulina phycocyanin liquid, 20-28 parts of gerbera, 23-26 parts of herba eupatorii, 18-22 parts of silybum marianum, 13-19 parts of ramulus uncariae cum uncis, 12-17 parts of willow leaves, 10-15 parts of ardisia maclurei merre, 8-13 parts of circaea quadrisulcata, 5-9 parts of willow-leaf cotoneaster, 4-8 parts of heracleum acuminatum, 3-6 parts of polygonum hydropiper, 2-5 parts of aeschynomene indica and 700-900 parts of rice. The method mainly includes working procedures of (1), preparing the rice; (2), preparing the spirulina phycocyanin liquid; (3), preparing traditional Chinese medicine liquid; (4), mixing the rice, the spirulina phycocyanin liquid and the traditional Chinese medicine liquid with one another to obtain mixtures; (5), drying and sterilizing the mixtures. The rice and the method have the advantages that phycocyanin in the fresh spirulina is sufficiently extracted and is uniformly mixed with the traditional Chinese medicine liquid to obtain mixed liquid, then the mixed liquid is sprayed on the surfaces of the rice, accordingly, the rice contains abundant phycocyanin nutrition, pharmacological effects of Chinese herbal medicines selected from raw materials further can be realized by the rice, and effects of clearing the heat, lowering the fire, removing toxicity and decreasing the fire can be realized by the rice.
