“First, do no harm” is an idea that goes back to the days of Hippocrates, the father of medicine in Western civilization.
If you order a formula that normally includes Fu Zi, you must contact us first to ensure that this herb is appropriate for you. If you do not contact us, the Fu Zi will be replaced by a similar herb.
Fu Zi (é™„å Prepared daughter root of Sichuan aconite, Radix Lateralis Aconiti Carmichaeli Praeparata) is an herb where dosage is carefully monitored. In its raw form, it is toxic and must be carefully cooked to reduce this toxicity. Even in the prepared extract form (which we carry at Eagle Herbs), we want to be sure to dose it correctly to avoid its normal benefits from becoming a problem in one who for instance, may not need interior warming.
Both of these herbs are roots and when these roots are diced up it can be difficult to visually differentiate between the two.
Knowing which you have can be important too, aristolochic acid (found only in the Guang Fang Ji – Aristolochia plant) is not good for the kidneys. However the Stephania root is an excellent diuretic and very safe to use.
Fortunately we have chemical analysis to know for sure which one we have.
In December of 2000, CRN, or the Council for Responsible Nutrition (a dietary supplement trade group) provided the United States Food and Drug Administration (US FDA) a report demonstrating the safe upper limit dosage for ephedra, known as “ma huang” in Chinese medicine.
This industry group sought to determine the safe dosages for ephedra since there were reports coming in of adverse events such as high blood pressure and heart attacks following the ingestion of extremely large dosages of this herb for energy and weight loss. These uses were inconsistent with their uses in Chinese medicine. Read More »
Chai Hu (Rx. Bupleurum) is a great herb for a variety of viral issues as well as stress-induced problems. Interferon therapy is designed to address viral issues as well. The interaction of Chai Hu (Rx. Bupleurum) and interferon is an additive problem. Interferon therapy boosts the strength and sensitivity of the immune system. Chai Hu (Rx. Bupleurum) has the same (but weaker) effect. When these two medicines are used together, they can give rise to an excessive immune response that damages the lungs. Read More »
This is really more about a “side-effect” than an interaction.
Long-term high-dose use of gan cao (Licorice root) is associated with changes in how the kidneys excrete water. If you retain more water, it is possible for blood pressure to rise. Reports of this issue describe dosages of 273 to 546 mg per day [source], and 1,000 mg per day [source]. The typical dosage of gan cao (Licorice root) used in Eagle herbs formulas varies between 10 – 20 mg per day. Not too much comparatively speaking. This is consistent with traditional uses of this herb. Read More »
