Government studies showed the dangers of these products decades ago yet it was brushed under the rug and is still actively used in nearly every household across the nation. Neural pathways are directly altered showing a direct link with GABA receptors, nerve impulses, dopamine and serotonin in the brain. Today scientists and the medical community actively report there are no adverse effects to the human body, however pyrethin itself proved differently and was reported years ago as a danger.

 PubMed said, “Certain types of neuronal ions channels have been demonstrated to be the major target sites of insecticides.” This means when insecticides are ingested they have a proven negative impact on the brain. There is no distinction showing a difference between residual pesticides on food, pesticides within food such as glyphosate or pesticides sprayed in the environment and inhaled. 

Neurotransmitters have different functions: glutamate activates the nerves to action; GABA is an inhibitory neurotransmitter which in essence prevents the freak out factor instead of the homeostasis of calm; dopamine and serotonin are involved with thought and cognition.

Pyrethrins have been heavily tested regarding interactions with brain pathways. The EPA says there are over 3,500 registered pyrethrin products. Most of these are used as household insecticides, pet insecticides, mosquito deterrents and agricultural use. The EPA adds, “Residential uses of pyrethrins and pyrethroids may result in urban runoff, potentially exposing aquatic life to harmful levels in water and sediment.”

PubMed says pyrethroid actions have been studied extensively regarding the voltage-gated sodium channel and cyclodiene/lindane actions on the GABAA receptor chloride channel complex. The conclusion is, “Neuronal ions channels have been demonstrated to be the major target sites of insecticides.” (This report, along with the PubMed info above, was printed in 1996).

Organophosphate and carbamate insecticides have been found to inhibit acetylcholinesterases, the hydrolase that hydrolyzes the neurotransmitter acetylcholine. Acetylcholine carries signals from the nerves to the muscles. When this channel is blocked or damaged the nerves can not speak to the muscles clearly. This could result in numbness in extremities, the tingly feeling that your arm or hand is falling asleep, etc.

Many different neurotransmitters are used for different jobs: glutamate excites nerves into action; GABA inhibits the passing of information; dopamine and serotonin are involved in the subtle messages of thought and cognition. The main job of the neurotransmitter acetylcholine is to carry the signal from nerve cells to muscle cells.

In reference to pyrethrins PubMed said, “Most insecticide commercially developed act on the sodium channel and the GABA system. Pyrethroids show the kinetics of both activation and inactivation gates of sodium channels resulting in prolonged openings of individual channels. This causes membrane depolarization, repetitive discharges and synaptic disturbances leading to hyperexcitatory symptoms of poisoning in animals.” (Again this is from the 1996 printing).

However, the belief of many scientists along with those in the medical community with an accompaniment of mass marketed pyrethroid products, somehow remains contradictory to the above concerns. This conflicting information is shocking.

In March of 2015, Dr. Johnson Matowo, parasitology specialist from Kilimanjaro Christian Medical University College, in conjunction with Duke University says, “Pyrethroids are the only class of insecticides approved for use with ITNs/LLNs (insecticide treated nets or long lasting insecticide treated nets) due to their rapid knock down effect and no adverse effects to humans.”

In 2013 PubMed again reported, “Most pyrethroid mosquito control products can be applied only by public health officials and trained personnel of mosquito control districts.” However, they did release approved pictograms for use on the product labeling. 

Pyrethrin type products originally came from chrysanthemum flowers, which contain the substance in smaller dosages than commercially produced sprays.

The Agency For Toxic Substances and Disease Registry, a devision of the CDC says, “Pyrethrins and pyrethroids can enter your body if you swallow drinking water contaminated with these compounds, but since pyrethrins and pyrethroids are rarely found in drinking water, this will be a minor exposure route.”

They go on to say, “These compounds are broken down in the body quickly.” They say the exposure to eating vegetables with the pesticide is minimal however eating the dirt the vegetables are ground in would be more damaging as it hold onto the chemical where the vegetable does not, they claim. They say the same with ingestion vs dermal contact, they claim.  They add parameters saying, “The EPA has recommended daily oral exposure limits for 10 different pyrethroids. These limits range from 0.005 to 0.05 mg/kg/day.”

Drugs.com says, “Medicine containing pyrethrins is used to treat head, body, and pubic lice infections. pyrethrum extract and piperonyl butoxide is absorbed by the lice and destroys them by acting on their nervous systems. It does not affect humans in this way.”

The National Pesticide Information Center says, “Pyrethrins are practically highly toxic to honey bees.” They go on to add, “Pyrethrins are highly to very highly toxic to fish. They are also very highly toxic to lobster, shrimp, oysters, and aquatic insects. Long term exposure to pyrethrins can cause reproductive effects in fish and aquatic insects. In separate studies, minnows and water fleas were exposed to very small amounts of pyrethrins for one month. Fewer minnow eggs hatched and fewer water flea young were produced.”

In addition they say, “Dogs fed extremely large doses of pyrethrins have experienced drooling, tremors, uncoordinated movement, and difficulty breathing. Increased activity, exhaustion, convulsions, and seizures have also been reported with high doses.”

Still The National Pesticide Information Center claims, “Pyrethrins are low in toxicity to people. They are absorbed poorly by skin contact. Once inside, they are rapidly broken down into inactive products and are removed from the body.”
