Dit las ik op een Amerikaanse site waar ik veel kom. Misschien moeten we met z'n allen aan't tuinieren, want ik vind het veelbelovend klinken...
Ben er nog niet achter of je dit dan rond je stal moet planten of je paard te eten geven, maar die vraag heb ik inmiddels al gesteld, en hoop spoedig op antwoord... Als ik meer weet horen jullie het.

CATNIP DRIVES CATS WILD, BUT DRIVES MOSQUITOES AWAY
AMES, Iowa -- Although it drives cats wild, catnip appears to be a big turn-off for mosquitoes.
In research conducted at Iowa State University, catnip was 10 times more effective at repelling mosquitoes than the compound used in most commercial bug repellents. The finding was reported today at the 222nd national meeting of the American Chemical Society in Chicago.
Chris Peterson and Joel Coats studied the effect of nepetalactone on mosquitoes. Nepetalactone is an essential oil in catnip that gives the plant its odor. In past studies, the researchers had found that catnip oils could repel cockroaches. Peterson recently left a post-doctoral research position at Iowa State and is now working as an entomologist with the U.S. Forest Service in Starkville, Miss. Coats is the chair of ISU's Department of Entomology.
The researchers placed groups of 20 mosquitoes in a glass tube treated on one side with a high dose of nepetalactone. After 10 minutes, an average of 80 percent of the mosquitoes had moved to the untreated side of the tube. In a low-dose test, an average of 75 percent moved to the untreated side.
The researchers conducted similar tests with DEET (diethyl-meta-toluamide), the compound used in many commercial repellents. In those tests, 55 to 60 percent of the insects moved away from the treated side.
In the laboratory, repellency is measured on a scale from 100 percent (all mosquitoes repelled) to -100 percent (all mosquitoes attracted). In the ISU tests, catnip ratings ranged from 49 to 59 percent at high doses, and 39 to 53 percent at low doses.
Peterson said it took about a tenth as much nepetalactone to have the same repellency as DEET. "In other words, nepetalactone is about 10 times more effective than DEET," he said. "Most commercial insect repellents contain about 5 to 25 percent DEET. Presumably, much less catnip oil would be needed to achieve the same repellency as a DEET-based repellent."
Why catnip repels mosquitoes remains a mystery. "It might simply be an irritant," said Peterson, "or they just don't like the smell."
No animal or human tests are scheduled for nepetalactone, although Peterson is hopeful that will take place in the future. Iowa State has submitted a patent application for the use of catnip compounds as insect repellents. The project was funded by the Iowa Agriculture and Home Economics Experiment Station.
Catnip is a perennial herb in the mint family and grows wild in most parts of the United States. It also is cultivated for commercial use. It's primarily known for its stimulating effect on cats, although some people use the leaves in tea, as a meat tenderizer and as a folk treatment for fevers, colds, cramps and migraines. The plant also is used to make light yellow dye.
The above info was taken from The Iowa State University Website, dated 8/2001. I thought it was very interesting.

Dit is een interessant artikel over verschillende kruiden die gegeten (grazen) kunnen worden.

Overigens zijn ze in Amerika op dit moment erg fel om muggen bij paarden vandaag te houden vanwege de White Nile Disease die aardig bezig is in Amerika.

Niet alleen bij paarden... er zijn ook al een aantal mensen aan overleden...

Volgens mij, als ik het artikel goed lees, moet er uit het kattekruid olie worden getrokken wat je dan over je paard kan smeren/ sprayen oid...

Zou wel mooi zijn als dit nu eindelijk wel werkt!
