So let's think about parasites for a minute.
At any one time a creature (including many humans - ick I know) will have all stages of a parasite or parasite types from eggs to juveniles to adults within their system over an average of a 21 day life cycle. The most common ones get into systems by ingestion. Whether that is eating contaminated food in a feeder, off the ground or in the pasture or drinking contaminated water. Eggs, larvae, flea bites, slug ingestion, inhaling airborne worm ovum and even skin contact with some such as hookworm. Some of these live off of the food in the GI Tract, some of them attach to the host and live off of the nutrients in the blood stream or even the blood itself.
Now thinking like a Vitalist (cause oriented) rather than an allopath (symptom oriented) let's think about using an extract for GI System residing parasites. Yes it can be effective. In those cases you will want to fast the animal so that the extract comes into physical contact with more of the parasites in the intestines as it moves through them. It will of course also be absorbed into the blood stream and run through cells and for those parasites drinking blood they will be getting it in their lunch. Now if you are working with a ruminant keep in mind that very little of the product will make it into the intestines, but it will still make it into the bloodstream. So in my opinion as a Master of Herbology extracts are best used for simple stomached creatures as well as for parasites that reside in other areas of the body. For many people extracts are easier to give as they can be added to waters or carefully given by dropper by mouth in the case of smaller pets.
Now consider using an herb powder. Herb powders, on the average, in a reasonably healthy stomached individual will start absorbing phytochemicals (plant nutritional components) into the bloodstream in about twenty minutes. In ruminating animals more of that product is then put into the cud, chewed further and then a much larger percentage makes it into the intestinal tract. You also have a larger amount of plant mass entering the rumen and / or intestinal tracts then you do with an extract, so that more herb is coming in direct contact with worm ovum and parasite bodies. So for GI residing parasites in animals and especially those still eating (not fasting which is dangerous for milking stock and third trimester stock) my personal preference is to use high quality whole herb powder products that are synergestically blended.
We offer two: DWA(tm) and GI Soother(tm). Both products can be responsibly used with any age and type of animal with no milk, meat, egg or pregnancy withdrawals.
GI Soother(tm) is incredibly popular with raising youngstock and especially for foreign living matter that can hemorrhage a creature quickly.
DWA(tm) is useful for foreign living matter issues occuring in multiple body locations.
Both products support the body's attempt to do what it was created to do in these situations.
For animals that are really struggling we also encourage the use of MMune(tm) to give the body additional immune system support.
For animals that are or have been really struggling we also like to consider BetterDaze(tm) for additional wellness support with its very mindful collection of herbs historically used for a wide range of phytochemical components.
Here's to a very happy and healthy season for you and all of the creatures under your loving care!
