• Ivermectin

    Posted by theholisticgoat on June 22, 2023 at 9:19 am

    I posted this in the THG FB group in Oct 2021. The original Stanford article I quoted can no longer be found on their website, which is why I save copies of each article I link here, so we can see the original text no matter what. I wish I’d done that with this, but here is the quote remaining from the post. Use this thread to discuss all things related to Ivermectin.

    “From a holistic standpoint, Ivermectin is something I want to avoid at all costs. Not only is it depleting the health of the animal it is administered to, but also the ecology of the soil the excess is deposited in.

    Even in “holistic” groups, Ivermectin is commonly recommended as a remedy for things that herbs and minerals can easily handle, such as external parasites. If we are holistically managing our herds, we must also pay attention to our soil impacts because healthy soil contributes to healthy animals and the reverse is also true.

    Ivermectin and other conventional dewormers should, in my opinion (and my own practice) be used as an absolute last ditch effort to save a life. I’ve not had an experience since going 100% herbal where I needed to use conventional meds though.

    Here’s a paragraph from the linked summary [now defunct] of some studies showing Ivermectin effects:

    ‘Studies of livestock have found that the presence of avermectins slow the degradation of dung due to its harmful effects on dung insects. At high levels, larvae are killed or paralyzed while at lower levels, their metamorphosis is inhibited, resulting in decreased adult emergence and significant morphological abnormalities. (Strong, L) Ivermectin may also pose a risk to springtales and earthworms, namely enchytraeids. (Jensen et al 2003). Other studies indicate that Ivermectin is not toxic to earthworms at concentrations typically found in soils. {Bloom, 1993 #22}Another study however found that ivermectin at environmental concentrations do not pose much risk to several strains of fungi.

    The FDA’s own environmental impact studies found that free Ivermectin may demonstrate considerable acute toxicity to crustaceans and fish, particularly Daphnia. However, because ivermectin is not very soluble in water and is very strongly absorbed by soil, there should be little free ivermectin in the water before it settles in the sediment.(Bloom and Matheson 1993)

    The topica application of ivermectin also poses problems for the potential for avian toxicity. Birds may ingest hair containing famphur from cattle treated topically with Ivermectin. Henny et al. (1985) found evidence that the drug may cause the death of magpies and secondary poisoning of raptors.'”

    “A single injection of calves with ivermectin, at the recommended anthelmintic dose rate of 200 μg/kg of body weight, was effective in killing the larvae of the dung-breeding dipteran, Orthelia cornicina for up to 32 days post-treatment. Newly emerged beetles of the scarabaeine dung beetle, Copris hispanus, suffered 90 % mortality in dung dropped on days two and three after injection and 27.5 % mortality in dung of day 16. Feeding activity was greatly suppressed in dung of days 1–8, but was normal in dung of days 32 and 64, in which there was no substantial mortality. In the 1–16 day treatments, survivors showed aberrant reproductive development. When ovipositing C. hispanus were fed with day 3 dung, there was no adult mortality but oviposition rate was reduced and immature survival was zero. No mortality occurred among sexually mature adults of the dung beetle, Bubas bubalus when fed for five weeks on dung collected at intervals ranging from 1–32 days after injection. Substantial mortality was recorded among newly emerged beetles of Onitis belial, following exposure to ivermectin residues. Environmental implications of these results are discussed.”
