I would suggest to start reading Ask Andreas Moritz Forum every day. He follows the Ayurvedic protocol.
I don't think he has talked about triphala, but it has been mentioned before on another forum.
Andreas does suggest Oxypowder or colosan. Colosan might be cheaper than Oxypowder (capsules) because it comes in powder form and you have to mix it yourself. In his books he also mentions caster oil and aloa vera (sp?). His books are copyrighted, but you can buy them from his website.
He also suggests an Epsom Salt cleanse. Look through the messages on this page, or before, it was just discussed.
