Does color therapy really help in healing?

I've been searching for cure of my peptic ulcer through alternate treatment methods. One site I've found suggests to drink "color water" prepared by using different color bottles kept in sunlight. There are treatments of other diseases mentioned too by using this color and light therapy. I would like to know if anyone here already knows about such method really working and benefiting? Here's the website address:
