Szechuan peppercorn (Xanthoxylum piperitum) is not a member of the pepper family. It is the outer pod of the tiny fruit of a plant related to prickly ash. It is known in Chinese as (山椒) Shan jiao or (花椒) hua jiao, in Japanese as (山椒) sansho and in Tibetan as emma. Tibetans believe it can sanitize meat that may not be so fresh.
