Sweetener to your taste; you can use honey, sugar, or stevia.
Instructions
Select a large, heavy-bottomed pot. Turn the stove on to medium heat and put all the water into the pot. Then add the roasted barley, boldo leaves, plantain leaves, cat's claw, lemon balm leaves, lemongrass leaves, horsetail, and pineapple rind. Stir with a large spoon, and start cooking, cook for about an hour.
After an hour, the herbs will be cooked and the water will be light yellow. It is time to add the flaxseed and the lime juice. Flaxseed is not added early on because it tends to stick out of the bottom. Cook uncovered for an additional half hour.
At the end of cooking, the water will have reduced by up to a third, and the consistency of the emoliente will be slightly gelatinous. Turn off the stove and let it sit for a couple of hours at room temperature until completely cool. At this point you just need to strain it and add the sweetener of your choice. If you prefer, you can also add a little extra lime juice. Remember that this drink can be taken hot or cold.
