Humaworm also offers Hu-Mana-Tea which is his version of the Essiac tea. You might compare his price to what you are paying for the Essiac next time you order the humaworm. Per his dosing, agressive is 9-12 ounces per day broken down into 3-4 ouces 3 times per day, moderate 6-9 oz/day 3 X's per day, preventative 3 oz/day 3 X's per day. I would think the Essiac tea would be a similar dosage. It can be deliuted with juice or whatever for taste if needed. I found just taking a shot glass down the hatch just fine. I like the taste!
The in-between herbs that are recommended 1/4 teaspoon each of the following: garlic, onion, sage, thyme, ginger, cloves and cinnamon. Just incorporate these into your daily food intake. You can use the powdered ones found in any spice section. Maybe this would help since you are limited on the products available?
