Laxative Tea

Now this can be used in place of the Sea Salt Flush. I suggest you give the sea salt a go as it is more effective but you may find that you struggle to tolerate it.
There are many brands available; try these Laxative Teas

Psyllium Husk

Psyllium husk is another form of laxative; it's good to have a variety to choose from, especially if you find some of them harder to take. Psyllium husk is very fiber rich, the other big advantage is that it is the closest thing to real food you will be able to eat during the Master Cleanse.
It comes in powder form and capsules; check out Apple Flavored Psyllium

Wheat Grass

Wheat grass has a high nutritional value; it contains chlorophyll, enzymes and vitamins A, B complex, C and E, trace elements calcium, iron, magnesium and potassium, and amino acids.
Wheat grass is also a powerful antioxidant that can help boost your immune system therefore it's great for detoxing. More importantly, wheat grass contains protein. Lack of protein is one of the biggest downsides to the traditional Master Cleanse, but wheat grass will not interfere with the cleansing process.
