Ginger For Hypopigmented Scars

Can anyone attest that using fresh ginger works to heal/return pigment to hypopigmented scars? I was doing a search on hypopigmented scars and found a peculiar blog about how "passing over" fresh ginger onto hypopigmented scars will heal them.

The exact quote is:
------
I was referred by a friend to an old Chinese man who practices alternative medicine from his home. He told me to start using the juice of fresh ginger roots on my vitiligo.

Buy fresh ginger roots. Go home and wash the roots to rinse off soil and chemicals. Cut off a slice of the root and pass it over the discolored areas. Do not rub! When that slice dries out, cut another slice and do the same thing again. Do that everyday. Don't forget. You can also do it a couple of times a day. You DO NOT need to go out in the sun. You DO NOT need the ultraviolet sessions. You can QUIT everything else you're using.

(...)A healthy cell has to communicate with a neighbor discolored cell and 'tell it' to begin producing melanin. But the ginger roots have some type of property that 'teaches' the cells to begin producing melanin SPONTANEOUSLY, from inside out.

The entire blog's 5 entries are devoted to this specific topic (ginger for hypopigmentation) and is written sort of gimmicky . But why would someone go at great lengths to make something this obscure up? Especially if it didn't work. There's nothing for sale on the blog and I can't see how the author would make any profilt.


I'm about to try this on a hypopigmented scar I've had for a few years now, but wanted to know what some of you think. It wouldn't suprise me if works greatly and is hardly known at all, seeing as ginger basically costs nothing and no big companies can make a profit from its sale.

Also the site's quotes mention to use the juice of fresh ginger, but then says to simply "pass" the ginger over the scar until it dries (not rub). I'm not quite sure what that means.. Maybe I should try squeezing a little juice on the scar?
