Do American feverfew herbal supplements contain the same ingredient as Chinese chrysanthemum tea?

be careful with feverfew.

Some people are very alergic to it. If you experience your throat swelling stop taking it.

I am alergic to feverfew

If the herbal supplements you are taking are either tablet or capsule, you are not getting the potency you desire. The tablets contain at least 5% Magnesium Stearate of the total mg of listed ingredients! Magnesium Stearate is a hydrogenated oil (transfat) that inhibits the immune system. 5% of 1,000 mg. is 50 mg of this garbage you are ingesting with each pill. This has been shown to inhibit the potency from about 90% without the Stearate to about 40% with it. The pill manufacturers use this to allow the pill to release from the machines. Also, look for Silica. That is sand. Are you deficient in sand? I don't think so.

The capsule people are just as bad. These things are typically made from Cow Hooves where you can have things like prion in them. These capsules, made of gelatin from cow hooves, inhibit the absorption of the ingredients by as much as 50%.

A study was done of health food vitamins and supplements and shown that 97.5% of them had some form of toxic ingredients, synthetic nutrients to boost the natural ingredients listed, aged herbs, incorrectly mixed herbs, grade 1 or 2 herbs, or some other problem!

One site that has grade 10 herbs and none of the above problems is: www.healthline.cc

Good luck to you. It's not pretty out there.
