Quotes from Chinese historical sources
THE HERBAL CLASSIC OF SHEN-NONG: "Treats tightness in the chest, coughing or dyspnea caused by abnormal rising of lung-qi, diarrhea and dysentery by warming the spleen and stomach, arresting bleeding, inducing diaphoresis and relieving arthralgia due to wind-dampness. The raw herb is especially good."
THE COMPENDIUM OF MATERIA MEDICA: "Dried ginger... has four functions: firstly, it activates heart-yang; secondly, it removes deep and stubborn cold from the zang-organs and fu-organs; thirdly, it expels cold-qi from the channels; fourthly, it treats abdominal pain due to the effects of cold."
A REALISTIC APPROACH TO HERBS: "Being very hot and non-toxic, the potency of the dried ginger remains at a fixed position without any movement. This herb will have immediate effects in recovering depleted yang if used together with monkshood root (Radix Aconiti Praeparata) in the treatment of deficiency-cold in the stomach and the threatened exhaustion of primordial yang. Therefore, the medical books state that monkshood root will not be hot without ginger."

Inhibition of gastric H(+),K(+)-ATPase and Helicobacter pylori growth by phenolic antioxidants of Zingiber officinale.
Siddaraju MN, Dharmesh SM.
Department of Biochemistry and Nutrition, Central Food Technological Research Institute, Mysore, Karnataka, India.
Ulcer is a common global problem characterized by acute gastric irritability, bleeding, etc. due to either increased gastric cell proton potassium ATPase activity (PPA) or perturbation of mucosal defence. Helicobacter pylori has been identified as a major ulcerogen in addition to oxidative stress and nonsteroidal anti-inflammatory drugs. In this paper, we report ginger-free phenolic (GRFP) and ginger hydrolysed phenolic (GRHP) fractions of ginger (Zingiber officinale) as potent inhibitors of PPA and H. pylori growth. GRFP and GRHP inhibited PPA at an IC(50) of 2.9 +/- 0.18 and 1.5 +/- 0.12 mug/mL, exhibiting six- to eight-fold better potency over lansoprazole. GRFP is constituted by syringic (38%), gallic (18%) and cinnamic (14%) acids and GRHP by cinnamic (48%), p-coumaric (34%) and caffeic (6%) acids as major phenolic acids. GRFP and GRHP further exhibited free radical scavenging (IC(50) 1.7 +/- 0.07 and 2.5 +/- 0.16), inhibition of lipid peroxidation (IC(50) 3.6 +/- 0.21 and 5.2 +/- 0.46), DNA protection (80% at 4 mug) and reducing power abilities (80-338 U/g) indicating strong antioxidative properties. GRFP and GRHP may thus be potential in-expensive multistep blockers against ulcer.

OBJECTIVE: To study the effectiveness of ginger for prevention of nausea and vomiting after gynecological laparoscopy. MATERIAL AND METHOD: From July 2005 to October 2005, 60 inpatients who underwent laparoscopic operations for non-cancer gynecologic conditions at Bangkok Metropolitan Administration Medical College or Vajira Hospital were randomized into Group A (n = 30) or Group B (n = 30). Group A received 3 capsules of ginger (1 capsule contained 0.5 g of ginger powder) while Group B received 3 capsules of placebo. Both groups received their medicine 1 hour prior the operation. Nausea and vomiting were assessed with the Visual Analogue Scores (VAS) and presence of vomiting at 2 and 6 hours after the operation. RESULTS: Median VAS at 2 hours post operation of Group A was not significantly different from that of Group B with the median of 0 (range, 0-5.4) and 0.15 (range, 0-10) respectively (95% CI from -2.59 to 0.90 and p = 0.142). At 6 hours post operation, the median VAS of Group A was significantly lower than group B, 0.55 (range, 0-7.4) versus 2.80 (range, 0-10) (95% CI from -3.61 to -0.73 and p = 0.015). Presence of vomiting at 2 hours was not different between the two groups, 10% in Group A and 20% in Group B (95% CI from -28% to 8% and p = 0.278). At 6 hours, 23.3% of group A had an episode of vomiting compared to 46.7% of group B (95% CI from -47% to 1% and p = 0.058). CONCLUSION: Ginger has shown efficacy for prevention of nausea and borderline significance to prevention vomiting after gynecological laparoscopy at 6 hour post operation.

Ginger--an herbal medicinal product with broad anti-inflammatory actions.
Grzanna R, Lindmark L, Frondoza CG
RMG Biosciences, Inc.
The anti-inflammatory properties of ginger have been known and valued for centuries. During the past 25 years, many laboratories have provided scientific support for the long-held belief that ginger contains constituents with antiinflammatory properties. The original discovery of ginger's inhibitory effects on prostaglandin biosynthesis in the early 1970s has been repeatedly confirmed. This discovery identified ginger as an herbal medicinal product that shares pharmacological properties with non-steroidal anti-inflammatory drugs. Ginger suppresses prostaglandin synthesis through inhibition of cyclooxygenase-1 and cyclooxygenase-2. An important extension of this early work was the observation that ginger also suppresses leukotriene biosynthesis by inhibiting 5-lipoxygenase. This pharmacological property distinguishes ginger from nonsteroidal anti-inflammatory drugs. This discovery preceded the observation that dual inhibitors of cyclooxygenase and 5-lipoxygenase may have a better therapeutic profile and have fewer side effects than non-steroidal anti-inflammatory drugs. The characterization of the pharmacological properties of ginger entered a new phase with the discovery that a ginger extract (EV.EXT.77) derived from Zingiber officinale (family Zingiberaceae) and Alpina galanga (family Zingiberaceae) inhibits the induction of several genes involved in the inflammatory response. These include genes encoding cytokines, chemokines, and the inducible enzyme cyclooxygenase-2. This discovery provided the first evidence that ginger modulates biochemical pathways activated in chronic inflammation. Identification of the molecular targets of individual ginger constituents provides an opportunity to optimize and standardize ginger products with respect to their effects on specific biomarkers of inflammation. Such preparations will be useful for studies in experimental animals and humans.

Anti-tumor promoting potential of selected spice ingredients with antioxidative and anti-inflammatory activities: a short review.
Laboratory of Biochemistry and Molecular Toxicology, College of Pharmacy, Seoul National University, 151-742, Seoul, South Korea.
A wide variety of phenolic substances derived from spice possess potent antimutagenic and anticarcinogenic activities. Examples include -gingerol, a pungent ingredient present in ginger (Zingiber officinale Roscoe, Zingiberaceae) and capsaicin, a principal pungent principle of hot chili pepper (Capsicum annuum L, Solanaceae).

Effect of ginger (Zingiber officinale Rosc.) and fenugreek (Trigonella foenumgraecum L.) on blood lipids, blood sugar and platelet aggregation in patients with coronary artery disease.
Bordia A, Verma SK, Srivastava KC.
Department of Medicine, R.N.T. Medical College, Udaipur, India.
In a placebo-controlled study the effect of ginger and fenugreek was examined on blood lipids, blood sugar, platelet aggregation, fibrinogen and fibrinolytic activity. In patients with CAD powdered ginger did not affect ADP- and epinephrine-induced platelet aggregation. Also, no change in the fibrinolytic activity and fibrinogen level was observed. However, a single dose of 10 g powdered ginger produced a significant reduction in platelet aggregation. Ginger did not affect the blood lipids and blood sugar.
