In a previous report (Sasaki et al. 2007), we described a
strong anti-tumor activity of the black garlic (extracts) in
the Meth A fibrosarcoma model of BALB/c mice, which
showed a 50% cure rate with no direct cytotoxicity of the
extracts against tumor cells in a test of mixture cultivation
of extracts and tumor cells. These results suggested the
probable association of the enhanced immune system due to
bio-functional potency of black garlic (extracts) to eradicate
transplanted tumor cells (Sasaki et al. 2007). In this paper,
we present the immune enhancement potency of black garlic
(extracts), which is possibly associated with the eradication
of tumor cells in this mouse model.
