Cassia angustifolia is an Asian herb that is used as a natural laxative and diuretic. More commonly known as senna, the leaves of this herb are made into a tea and marketed as a weight-loss aid under the brand name Slim-Mate. While proponents of cassia angustifolia senna tea claim it helps dieters shed unwanted pounds, the medical community argues that any weight loss is temporary at best, resulting from the increased elimination of waste matter. Use caution when performing a senna tea diet cleanse to avoid unwanted side effects.
Dilute the tea at the start of the diet cleanse to avoid stomach irritation. Place one tea bag into a saucepan filled with 4 cups of boiling water. Cover the pan, move it off the heat and allow the tea bag to steep for three minutes.
Drink 1 cup of the diluted tea in the morning and at bedtime for the first two days of your diet cleanse. Store the reserved tea from the diluted tea batch in your refrigerator.
Place one tea bag in the bottom of a teacup or mug. Add 1 cup boiling water. Allow the tea bag to steep for two minutes.
Drink one cup of the full-strength tea at bedtime for up to 10 days.
Take a potassium supplement during the senna tea diet cleanse to reduce the tea's potassium-reducing effects. The recommended daily intake of potassium is 4.7 g, according to the Colorado State University Extension. Use the potassium supplement as directed on the bottle.
Drink plenty of liquids to keep yourself well-hydrated during the diet cleanse. Take in at least eight, 8 oz. glasses of water per day; 100 percent juice or unsweetened teas are also good choices. Green and oolong teas have the added benefit of helping to increase your metabolism.
