No, this isn't a matter of homeopathic "like treats like." It's the pollen of ragweed (Ambrosia) that causes the allergies - not the rest of the plant. You can purchase ragweed tincture commercially, or you can send a friend out to gather and tincture it for you. The easy way to make a ragweed tincture via Simpler's method is to stuff a clean glass jar with everything but the root, then cover the plant in the purest, strongest grain alcohol you can get. Cover it tightly and wait for about two weeks. Then strain out the herb. (You can do this part; the pollen is too drunk to fly at you by then.) Whether you buy it or make it yourself, the dosage is the same: 20 to 40 drops up to 4 times a day.
You can prepare a ragweed tea, too. You'll definitely want someone else to collect the herb for you, then bundle and hang it until dried. Have them hide it far and away from you. Once it's dry, it can be crunched up and stored in a glass jar. Prepare a standard infusion of the tea by pouring a mugful of almost boiling water over a teaball of herb. Allow it to sit for about 15 to 20 minutes before straining. Drink about 1 or 2 ounces of it up to 4 times a day.
There's something slightly revengeful about combatting allergies by ripping up the offending plant and ingesting it, don't you think? Or perhaps ragweed doesn't really mean us all that harm and tries to make up for it. Either way, it's pretty cool, don't you think?
