Thrangu Rinpoche says that all deities are very similar in that they devote themselves to helping sentient beings. But beings have many different propensities and karma, so the deities manifest in different forms.
The Medicine Buddha looks similar to the Shakyamuni Buddha touching the ground, but he is the color of lapis lazuli. In his left hand in meditation mudra he a bowl of medicinal amrita and in his right hand he holds a medicinal (myrobalan) plant in the giving mudra. This photograph shows the Medicine Buddha alone on a lion's throne.

Thrangu Rinpoche has also written a book on the Medicine Buddha Practice. This is available in the Books section of this website.
