Figure 4. Effects of Ganoderma oil from different sources on tumor cell death.

(a) Breast carcinoma cells (MT-1) were treated with Ganoderma oil prepared from the standard protocol (WYGO-070102), 2-year-old (maintained at room temperature) Ganoderma oil prepared from the standard protocol, and a sample of Ganoderma oil obtained from a different source (XZL-Z). Analysis of the half maximal effective concentration (EC₅₀) indicated that the Ganoderma oil prepared from the standard protocol produced the best result in inducing tumor cell death, followed by the 2-year-old product and the sample from a different source. (b) MT-1 cells were treated double-blindly with Ganoderma oil obtained from different sources. EC50 was obtained as indicated.
