Cinnamomum cassia component called coumarin, which could damage the liver if consumed in larger amounts, European health agencies have warned against consuming high amounts of cassia. Other bioactive compounds found in the bark, powder and essential oils of "C. cassia" are cinnamaldehyde and styrene. In high doses these substances can also be toxic for humans.

SPICE SPICE and comes preloaded with models for the company's integrated circuits. Analog Devices offers a similar free tool called ADIsimPE (based on the SIMetrix/SIMPLIS implementation of SPICE). Other companies maintain internal circuit simulators which are not directly based upon SPICE, among them PowerSpice at IBM, TITAN at Infineon Technologies, Lynx at Intel Corporation, and Pstar at NXP Semiconductor. SPICE became popular because it contained the analyses and models needed to design integrated circuits of the time, and was robust enough and fast enough to be practical to use. Precursors to SPICE often had a single purpose: The BIAS program, for
