A side effect of Xi Xin occurs when it is applied incorrectly. Because it is very hot and pungent, it can easily injure the Yin, blood, body fluid and Qi. It should not be used, or must be used with caution, in patients who suffer from exterior wind-cold syndrome where internal heat also coexists and the Yin, blood and body fluids are deficient. The dosage of Xi Xin should also be controlled carefully in the range of 1-3 g per day for crude herbs. If the powdered herbal extract is used, the dosage should be reduced to 0.1 -0.5 g per day. Overdose may cause numbness in the throat and tongue, a stifling...

The collected herbs were dried under sunlight or in oven at 40°C. The dried herbs were weighed and ground in powder. The powder was macerated with ethanol in a ratio of Ig 11 for 3 days. NaS04 was added to absorb water content in the mixture. The ethanol with herb powder was then filtered and evaporated with rotary evaporator at 30-35°C. The ethanolic extract was added with 200ml hexane. The mixture was left for 3 days. After that, the mixture was filtered to gain hexane extract. The residue was added with water and ethyl acetate to perform liquid-liquid extraction. Water layer was freeze-dried to obtain water extract.

So does echinacea work One would think that this would be a relatively simple question to answer, but it isn t. The best reply I can come up with is that some echinacea preparations work for some conditions in some people some of the time. I realize that this is not very satisfying, but such is the nature of the herbal beast. First of all there are nine species of echinacea, although manufacturers only use three (E. purpurea, E. angustifolia, and E. pallida) to make supplements. Each of these plants has a different chemical profile. Each contains dozens of compounds some they have in common, some they don t. Furthermore, their leaves, flowers, stems, and roots have different compositions. An alcohol extract of the root will have a very different chemical makeup from a hexane extract of the stem or from capsules filled with dried, powdered leaves. Before we even... 

Ephedra is available in multiple forms. It is a common ingredient in energy boosting bars, sold as Herbal Ecstasy in some health food stores, and is also available as powder that can be mixed with water. Health food stores may sell powdered ephedrine stems, which can be used in a tea, or they may sell infusion, extracts, tinctures, or tablets of ephedra. Health food stores may also sell ephedra as the ma huang herb. Many manufacturers tend to advertise or market ephedra supplements as natural or as a botanical herb, because some consumers equate natural with safe. In China, ephedra may be boiled with cinnamon twig, licorice root, and almond to treat the common cold. 

The Herbal Blend, composed of equal parts by weight of cinnamon bark extract (Cinnamomum zeylanicum), acerola fruit (Malpighia glabra), and Spanish needles powder (Bidens pilosa), was one of the first combination formulas assayed. Surprisingly, it showed synergistic inhibition of histamine release The sum of the inhibition of the three ingredients was 10.2% of control, whereas their combination inhibited histamine release to -52% (i.e., to below the concentration of histamine found in unstimulated cells). 

Other herbal materials prepared by roller compaction included St. John s wort (22) and Eschscholtzia californica Cham (23). Tableting of the granulated extract markedly reduced the problems associated with dust and material feed as well as the incidence of capping. Tablets produced from granulated extracts disintegrated three limes faster than those tabletted from the powder blend. Hygroscopicity of . californica Cham, extracts decreased after roller compaction due to decreased material surface area. 

Despite the potential toxicity that could be associated with many medicinal plants, the local people have for centuries been using them as recipes for traditional medicines. They have in many cases been able to effectively control possibilities of toxicity through knowledge handed down from forefathers. One way of eliminating potential toxicity of extracts by the herbal practitioners is by burning their herbal preparations before dispensing. This was evident in the present study where many of the herbal preparations used for skin infections would be burnt into powder first before application.
