HERBAL ALTERNATIVES TO ANTIBIOTICS AND ANTHELMINTICS



HERBAL ALTERNATIVES to ANTIBIOTICS and ANTHELMINTICS

Susun S. Weed, herbalist

Herbs are extremely effective in countering infections if used lavishly, repeatedly, and skillfully. Larger animals, like goats may be given tinctures directly into their mouths. I dose smaller animals, like dogs, cats, and rabbits, by adding tinctures to some liquid, usually milk.

Herbs That Counter Infecti

Echinacea (Echinacea purpurea or Echinacea augustifolia) is my mainstay anti-infective

Lomatium (Lomatium dissectum) is a specialty herb with broad-spectrum abilities

Goldenseal (Hydrastis canadensis) is not recommended.

Poke (Phytolacca americana) kicks the immune system into high gear.

Usnea (Usnea barbarata) is a lichen that counters deep-seated infections.

Yarrow (Achillea millefolium) says she runs a “school of self defense.”

I rely on echinacea root tincture, poke root tincture, and yarrow flower tincture for ninety-nine percent of all infections that I deal with. Occasionally I make use of usnea, and lomatium. I have used goldenseal only once in forty years of practice – externally, at that.

GOLDENSEAL is, I believe, overused. The plant itself is so overharvested that it has become rare in the wild. Consumers are enjoined to buy only cultivated root products in order to protect what little goldenseal is left. Goldenseal root, taken in any form, tea or tincture, kills and damages gut flora and, if used in large doses frequently, can stress and ultimately cause damage to the liver and the kidneys. I avoid it.

ECHINACEA is one of the most widely-used and most commonly-known of all herbs. I “discovered” it in the early 1970’s when looking for herbs to replace goldenseal in herbal formulae. In an old book of Eclectic herbs, I found Kansas Coneflower root listed as an effective agent against all infections. (Ask me what they called it in the book; I can’t write the name they used then as I would get in trouble for using a “bad” word nowadays.) I was able to procure both purple coneflower (E. purpurea) and large-leaved coneflower (E. augustifolia) roots, as plants for my garden and as dried herbs to use medicinally. I soon became enthralled with the beauty of the echinacea flowers and the power of her roots to heal.

It took me several years to learn that more is better with echinacea. I was cautious at first, treating it just like the antibiotic drugs I was familiar with. I limited my doses and limited the amount of time I used it. But as we grew to know each other, I stopped thinking of echinacea as a drug that could harm and began to regard her as a longevity tonic and an ally who could prevent as well as treat infections. (Let us remember that pharmaceutical antibiotics are not meant to be used to preventatively.) David Hoffmann, herbalist and author, reports that mice fed echinacea on a daily basis live twice as long as their echinacea-less litter mates.

I prefer to use E. augustifolia/angustifolia. It is difficult to cultivate, so I buy dried root and make my own tincture from it. (Instructions for making your own tincture are in all of my books and at my website: All my experiences relate to this species.

E. purpurea is the species most commonly offered for sale as a ready-made tincture. If made from the fresh root – and only the root (no leaves, no flowers, no seeds), and offered by itself (no goldenseal or other herbs mixed with it), E. purpurea is probably as effective as E. augustifolia. Echinacea has become a favorite landscaping plant. Purpurea grows rapidly, stays in flower for many weeks, is tolerant of drought, cold, and poor soils, and spreads through seeds.

The effective dose of echinacea root tincture is a large one, given frequently. How large? I use one drop per two pounds (or kilo) of body weight. A 300-pound goat needs 150 drops as a dose. A dropperful is generally about 25 drops, so 150 drops would be six dropperfuls. More is not a problem; less is not enough. I repeat the dose every one to four hours depending on the severity of the infection.

Echinacea nourishes the creation of white blood cells, up to, but not beyond, the capacity of the blood. (It can’t create leukemia, for instance). A blood test will show elevated levels of macrophages soon after the first dose. Continued use will help maintain the body’s ability to counter infective bacteria. Echinacea enhances the immune system; it is safe to use even when there is an auto-immune disease present.

When I raised chickens, I was horrified to find that all the feeds for chicks contained antibiotics. Instead, I added about an ounce of dried, ground E. purpurea root to a pound of feed. It worked well; but my chicks were not crowded, nor did I ever have more than a few dozen at a time.

POKE is a large, unusual-looking plant found primarily in rich soils in the eastern half of North America. The freshly harvested root, immediately tinctured, provides an agent that “pokes” the immune system and gets it going. Poke is one of the few scary plants that I use. All parts of it are considered poisonous if incorrectly prepared or used in excessive doses.

Country folk relish poke salat. A salat is a cooked green; young poke shoots are treated with boiling water to leach out the poisons and then cooked. I have enjoyed pokeberry jam and poke berry pie, although the seeds are quite poisonous. (So are apple seeds, apricot pits, and peach seeds.)

The dose of poke root tincture for people starts at one drop per day due to poke’s propensity for causing hallucinations when the dose exceeds ten drops a day. Poke contains many poisonous substances, including asparagene, an alkaloid that can damage the kidneys over time.

Since I don’t care if a sick animal hallucinates, I don’t hesitate to give large doses to them if I think it’s needed. If I don’t get the response I want from generous doses of echinacea given hourly for six hours in an acute situation, I bring on the poke. I generally add the poke tincture to the echinacea tincture in the ratio of one dropperful of poke per one ounce bottle of echinacea. Then I dose the echinacea as usual. Each dropper of echinacea contains about one drop of poke tincture.

I use poke only as needed. And never longer than is needed. It is especially effective in countering mastitis and engorgement of the udder from overeating proteins, such as alfalfa or acorns. Poke is not easily available. One source is www.redmoonherbs.com

YARROW counters infection, inside and out. The leaves or flowering tops, used fresh or tinctured is my favorite topical anti-infective. I discuss yarrow in my class (and notes) on treating injured animals. The tincture is for sale in most health food stores.

LOMATIUM has been shown to suppress the growth of sixty-two types of bacteria and fungi. It is also anti-viral, making it useful when the cause of the infection is uncertain. It is especially active in the mucus cells of the respiratory passages. It counters all colds and flus in humans and animals. Tincture of the freshly dug root, in doses as small as 5 drops taken three times a day, is used against brucellosis in goats and tuberculosis in humans; it is extremely useful in dealing with neonatal pneumonia. Lomatium tincture is not widely available. One source is

USNEA is a common lichen found on pine trees and fruits trees in cool, moist locations around the world. I have harvested usnea as south as New Zealand, as far north as Ontario, Canada, and as far west as California. It looks like old man’s beard and is related to it. The tincture of the properly-prepared plant is bright orange. Like lomatium, it has a special affinity for the lungs and respiratory organs. Like echinacea, it builds the immune system instead of stimulating it. Usnea is indicated if the infection is very deep-seated.

I use dropperful doses several times a day for mature animals with breathing difficulties. Dropperful doses, given every few hours, can counter rattles in the lungs of newborns. Usnea tincture is for sale in many places.

Chronic Wasting Diseases of Goats 2 Scrapie


I will not go into much detail as The Maryland Small Ruminant Page has an excellent review.

The following are abstracts from some of the Scientific Literature on Scrapie in Goats which some of you may find interesting.

State-of-the-art review of goat TSE in the European Union, with special emphasis on PRNP genetics and epidemiology.

Abstract

Scrapie is a fatal, neurodegenerative disease of sheep and goats. It is also the earliest known member in the family of diseases classified as transmissible spongiform encephalopathies (TSE) or prion diseases, which includes Creutzfeldt-Jakob disease in humans, bovine spongiform encephalopathy (BSE), and chronic wasting disease in cervids. The recent revelation of naturally occurring BSE in a goat has brought the issue of TSE in goats to the attention of the public. In contrast to scrapie, BSE presents a proven risk to humans. The risk of goat BSE, however, is difficult to evaluate, as our knowledge of TSE in goats is limited. Natural caprine scrapie has been discovered throughout Europe, with reported cases generally being greatest in countries with the highest goat populations. As with sheep scrapie, susceptibility and incubation period duration of goat scrapie are most likely controlled by the prion protein (PrP) gene (PRNP). Like the PRNP of sheep, the caprine PRNP shows significantly greater variability than that of cattle and humans. Although PRNP variability in goats differs from that observed in sheep, the two species share several identical alleles. Moreover, while the ARR allele associated with enhancing resistance in sheep is not present in the goat PRNP, there is evidence for the existence of other PrP variants related to resistance. This review presents the current knowledge of the epidemiology of caprine scrapie within the major European goat populations, and compiles the current data on genetic variability of PRNP.

Abstract

The bovine spongiform encephalopathy (BSE) crisis clearly demonstrated the need to keep animal transmissible spongiform encephalopathies (TSE) under control in order to protect animal and human health. Scrapie is the most widespread TSE of livestock in the world. For this reason, health authorities in different countries have elaborated plans that aim towards scrapie eradication. The unusual nature of the scrapie agent and the fragmented status of scientific knowledge about it, along with the limitations of currently available diagnostic tools, make it unlikely that the objective of eradication will be achieved in the near future. Scientific research is focused on acquiring the knowledge that will improve the efficiency of these efforts.

What veterinary practitioners should know about scrapie

Abstract

Scrapie is the longest known and most widely spread of the transmissible spongiform encephalopathies and remains the model for much of the research regarding these diseases. Because scrapie is a reportable disease and the subject of an active eradication program in the United States, veterinary practitioners should have a basic understanding of the disease.

Making Hay while the sun shines???

I never thought I would say, "Here comes the rain again, and again and again. What is this going to do to the hay crop? Good quality hay is a staple in western Canada for goats. Hay cut now will no doubt be rained on at least a couple of times; this reduces the quality and palatability dramatically. Protein digestibility will be reduced, Vitamin E and Vitamin A will leach out, and mould will reduce palatability. Moulds and bacteria feed on the nutrients of the hay as it lies in the swath decreasing the energy value. If the hay is left uncut waiting for, an opportune time the maturity will increase making it less palatable and the protein and energy levels will decrease. I f the hay growth is lush some of the trace minerals may not be taken up by the plant. The length of the rainfall and the timing of the rain after cutting can affect hay quality. Rain just after cutting is less harmful than a rain just prior to baling. A long steady rain leaches fewer nutrients out than an intense short downpour of equal amounts of rain. One rain shower of about 1 inch on hay during curing can cause yield losses of greater than 5 percent, reduce total digestible nutrients by 5 to 6 percent and reduce dry-matter intake by 8 to 9 percent.

Because of the unpredictable nature of our weather, the future of second cut hay and the green feeds harvested from cereal crops cannot be determined. However, it never hurts to plan ahead. This planning includes calculating the number of goats and groups of goats you anticipate feeding over the winter. With that information and what their nutrient requirements are, you can calculate how much feed plus a percentage you will need for the winter. If you are putting up your own hay or green feed, a nutrient analysis on properly taken and submitted samples is essential. Once this information is collected you can develop a feeding program, and purchase necessary supplements. The key to any successful feeding program is to plan. If you have to purchase forages then now is the time to start looking for them. Hopefully, you will not have to go too far afield and that you can trust the individual you are purchasing them from. Prior to purchasing the forages, you should have information about the quality of the forage and a guarantee from the seller that the forages delivered will be consistent with that information.

Living with Parasites

The Second edition of my goat production manual will finally be available sometime during the summer. Since the publication of the first edition in 1998 somethings have changed but many things remain the same. Parasite control and treatment has changed significantly,but still there are no deworming medications approved for goats in Canada.

Steps to Internal Parasite Control:

1)Identify the worm burden present in your goats:

This can be done by taking random fresh fecal samples from the various groups that you maintain. These fecal samples should be taken just prior to moving the goats from one area to new area as the old area may be contaminated but the a new area may notbe

The second edition outlines the procedures you can follow to do your own parasite identification and burden

2) Strategically Deworm

Once you establish the parasite burden in each group of goats than you can strategically dewormed them. Remember it is necessary for goats to have a small population of worms to maintain their immunity. Overzealous use or underdosing of deworming medications can lead too a population of parasites that are resistant to the dewormer.
