jeff,

here is some more info showing role of polyprenols in regenerating damaged livers

"[0010] Polyprenols or its derivatives are disclosed in patents and articles. Polyprenols are reported to be useful as pharmaceuticals or synthesis intermediates therefor, particularly as an antiviral agent, as an immunomodulatory agent, as cosmetics and for treating cancer (U.S. Pat. No. 4,668,820 to Ibata, et al., Russian patent number 2005475; L. L. Danilov, et al., Archivum Immunologiae and Thrapiae Experimentalis, 1996, 44, 395-400; A. V. Sanin, et al. Abstracts of the meeting "Dolichols and Related Lipids", Aug. 11-13, 1993, Zakopane, Poland; European Patent Application 0 350 801; Japanese Patent Application Laid-open No. 62-169724). In U.S. Pat. No. 4,613,593, phosphates of dolichol, a polyprenol isolated from swine liver, are stated to be useful in regenerating liver tissue, and in treating hyperuricuria, hyperlipemia, diabetes, and hepatic diseases in general. R. W. Keenan et al. state that it is important for organisms which rapidly keep growing, for example, those in the infant stage, to take dolichols extraneously so as to supplement the dolichols obtained by biosynthesis within their own body [Archives of Biochemistry and Biophysics, 179, 634 (1977)]."
