oil of chenopodium

extracted from the plant Chenopodium ambrosioides. An old-time anthelmintic.

oil-contamination

It also blocks nares, causes aspiration pneumonia, and has toxic effects on kidneys, reproduction and the gastrointestinal tract.

Animals do not do well and oil stays in the gut, appearing in the feces for long periods.

Patient discussion about thyme oil.

Q. if someone is allergic to olive trees, does that mean they are allergic to olive oil as well?

A. doesn't necessarily so, allergies are usually caused by all sort of proteins coming from all sort of places. olive trees might have a protein that won't show up in the oil. but if it's a severe allergy i wouldn't try it so easily. take it in an allergy test.

Q. Can omega-3 make my cholesterol lower? My doctor told me that I have too much cholesterol in my blood, and that it can cause heart attack or stroke, but if I keep it low than my risk will be lower. He told me that because it’s not that high level I can try to change my diet before I have to start taking medication. I heard that omega-3 can make my cholesterol level low. Is that true? Do I have to take it in pills? Is it safe?

A. You can consume omega-3 either as pills or in fish oil, fatty fish (such as salmon) and vegetarian food such as flaxseed and flaxseed oil, canola oil, soybean oil, and nuts.

Q. Does fish-oil helps exercise induced asthma? I was diagnosed with exercise induced asthma a couple of year ago, and since then had better and worse times with my asthma, although the treatment I get. I read in a newspaper that fish oil can help exercise induced asthma- is that true? Do I have to eat fish-oil specifically or can I eat fish instead (I really, really, hate fish-oil…)?

A. No one really proved that omega-3 actually helps asthma, although some doctors say it is. If I was in your situation, I’d just give it a try and see if it helps me (just ask your doctor before if omega 3 wouldn’t interfere with your other medications). Just remember that it’s not a magic, so don’t get disappointed if it doesn’t produce miracles on your asthma. Good luck!
