Used for Why
3 Stars
Morning Sickness
1 gram powder daily
Ginger, well-known for alleviating nausea and improving digestion, appears to be an effective and safe treatment for nausea and vomiting in pregnancy.

is well-known for alleviating nausea and improving digestion. One gram of encapsulated ginger powder was used in one study to reduce the severe nausea and vomiting associated with hyperemesis gravidarum. This condition is potentially life-threatening and should only be treated by a qualified healthcare professional. A review of six double-blind trials concluded that ginger is probably an effective treatment for nausea and vomiting in pregnancy.

Because ginger contains some compounds that cause chromosomal mutation in the test tube, some doctors are concerned about the safety of using ginger during pregnancy. However, the available clinical research, combined with the fact that ginger is widely used in the diets of many cultures, suggests that prudent use of ginger for morning sickness is probably safe in amounts up to 1 gram per day.

Motion Sickness
Adults: 500 mg one hour before travel and then 500 mg every two to four hours as necessary; children: 250 mg (half dose)
Ginger may help prevent and treat mild to moderate cases of motion sickness. Studies have shown it to be as effective as dimenhydrinate (Dramamine) but with fewer side effects.

may be useful for the prevention and treatment of mild to moderate cases of motion sickness. A double-blind trial examined the effects of ginger supplements in people who were susceptible to motion sickness. Researchers found that those taking 940 mg of powdered ginger in capsules experienced less motion sickness than those who took dimenhydrinate (Dramamine). Another double-blind trial reported that 1 gram of powdered ginger root, compared with placebo, lessened seasickness by 38% and vomiting by 72% in a group of naval cadets sailing in heavy seas. Two clinical trials, one with adults and one with children, found that ginger was as effective in treating seasickness as dimenhydrinate but with fewer side effects. In one controlled trial, though, neither powdered ginger (500 to 1,000 mg) nor fresh ginger (1,000 mg) provided any protection against motion sickness. Doctors prescribing ginger for motion sickness recommend 500 mg one hour before travel and then 500 mg every two to four hours as necessary. The study with children used one-half the adult amount.

Ginger’s beneficial effect on motion sickness appears to be related to its action on the gastrointestinal tract rather than on the central nervous system.

Osteoarthritis
510 mg daily of a concentrated herbal extract, taken in divided doses
Ginger has historically been used for arthritis and rheumatism. Studies have shown it to be effective at relieving pain and swelling in people with osteoarthritis.
has historically been used for arthritis and rheumatism. A preliminary trial reported relief in pain and swelling among people with arthritis who used powdered ginger supplements More recently, a double-blind trial found ginger extract (170 mg three times a day for three weeks) to be slightly more effective than placebo at relieving pain in people with osteoarthritis of the hip or knee. In another double-blind study, a concentrated extract of ginger, taken in the amount of 255 mg twice daily for six weeks, was significantly more effective than a placebo, as determined by the degree of pain relief and overall improvement.
2 Stars
Dysmenorrhea
250 mg four times per day, beginning at the start of menstruation and continuing for three days
In a double-blind trial, ginger powder was as effective as anti-inflammatory medication (mefenamic acid and ibuprofen) in relieving symptoms of dysmenorrhea.

Ginger has been used in some systems of traditional medicine to treat dysmenorrhea. In a double-blind trial, ginger powder was as effective as anti-inflammatory medication (mefenamic acid and ibuprofen) in relieving symptoms of dysmenorrhea. Ginger was used in the amount of 250 mg four times per day, beginning at the start of menstruation and continuing for three days. In another double-blind trial, 500 mg of ginger taken 3 times per day, beginning 2 days before menstruation and continuing for the first 3 days of the menstrual period, significantly decreased the duration and severity of menstrual pain, compared with a placebo. The treatment was somewhat less effective if it was started at the beginning of menstruation, rather than 2 days before.

Epilepsy (Asian Ginseng, Bupleurum, Cassia Bark, Chinese Scullcap, Jujube, Licorice, Peony, Pinellia)
2.5 grams a day of sho-saiko-to or saiko-keishi-to in tea or capsules
The Chinese herb bupleurum is included in two herbal formulas, sho-saiko-to and saiko-keishi-to. Both have been shown to be helpful for epilepsy.

The Chinese herb bupleurum is included in two similar Chinese herbal formulae known as sho-saiko-to and saiko-keishi-to; these combinations contain the same herbs but in different proportions. The other ingredients are peony root, pinellia root, cassia bark, root, jujube fruit, Asian ginseng root, Asian scullcap root, and licorice root. Both formulas have been shown in preliminary trials to be helpful for people with epilepsy. No negative interactions with a variety of anticonvulsant drugs were noted in these trials. The usual amount taken of these formulas is 2.5 grams three times per day as capsules or tea. People with epilepsy should not use either formula without first consulting with a healthcare professional.

2 Stars
Hepatitis (Asian Ginseng, Bupleurum, Cassia Bark, Chinese Scullcap, Jujube, Licorice, Peony, Pinellia)
Take 2.5 grams of sho-saiko-to three times per day
Trials have shown that the bupleurum-containing formula sho-saiko-to can help reduce symptoms and blood liver enzyme levels in people with chronic active viral hepatitis.

Preliminary trials have shown that the bupleurum-containing formula sho-saiko-to can help reduce symptoms and blood liver enzyme levels in children and adults with chronic active viral hepatitis. Most of theses trials were in people with hepatitis B infection, though one preliminary trial has also shown a benefit in people with hepatitis C. Sho-saiko-to was also found, in a large preliminary trial to decrease the risk of people with chronic viral hepatitis developing liver cancer. However, people who had a sign of recent hepatitis B infection were not as strongly protected in this trial. The usual amount of sho-saiko-to used is 2.5 grams three times daily. Sho-saiko-to should not be used together with interferon drug therapy as it may increase risk of pneumonitis - a potentially dangerous inflammation in the lungs.

Indigestion, Heartburn, and Low Stomach Acidity
2 to 4 grams daily fresh ginger or equivalent for indigestion
Ginger, with its anti-inflammatory and anti-nausea effects, has a history of use in treating gastrointestinal complaints, from flatulence to ulcers. It has been shown to enhance intestinal movements that aid digestion.

Carminatives (also called aromatic digestive tonics or aromatic bitters) may be used to relieve symptoms of indigestion, particularly when there is excessive gas. It is believed that carminative agents work, at least in part, by relieving spasms in the intestinal tract.

There are numerous carminative herbs, including European angelica root (Angelica archangelica), anise, Basil, cardamom, cinnamon, cloves, coriander, dill, , oregano, rosemary, sage, lavender, and thyme. Many of these are common kitchen herbs and thus are readily available for making tea to calm an upset stomach. Rosemary is sometimes used to treat indigestion in the elderly by European herbal practitioners. The German Commission E monograph suggests a daily intake of 4–6 grams of sage leaf. Pennyroyal is no longer recommended for use in people with indigestion, however, due to potential side effects.

Demulcents herbs may be used to treat indigestion and heartburn. These herbs seem to work by decreasing inflammation and forming a physical barrier against stomach acid or other abdominal irritants. Examples of demulcent herbs include , licorice, and slippery elm.

Ginger is a spice well known for its traditional use as a treatment for a variety of gastrointestinal complaints, ranging from flatulence to ulcers. Ginger has anti-inflammatory and anti-nausea properties. Ginger has been shown to enhance normal, spontaneous movements of the intestines that aid digestion.

Pre- and Post-Surgery Health
1 gram of powder in a capsule 60 minutes before receiving general anesthesia (inform your anesthesiologist)
Ginger has antinausea properties and may prevent postoperative nausea and vomiting.

A recent study found that 24% of surgery patients had taken herbal supplements before their surgeries, and 50 different herbs had been used among these patients. Little research exists, however, on the safety or efficacy of herbs before surgery. Some researchers and healthcare providers are concerned about possible harmful interactions between herbs and medications used around or during surgery, or the possibility that some herbs may increase bleeding during and after surgery. The use of herbs around the time of surgery should be discussed with a knowledgeable healthcare practitioner.

Nausea and vomiting can be experienced post-operatively as a result of anesthesia.  (Zingiber officinale) has antinausea properties and has been examined for its ability to prevent post-operative nausea and vomiting in several controlled trials. In two of these controlled trials, ginger was found more effective than placebo and equal to an antinausea medication; however, in two other controlled trials ginger was not found to have any benefit. A review considering the results of these trials concluded that 1 gram of ginger taken before surgery prevents nausea and vomiting slightly better than placebo, but this difference is not significant. However, a more recent review concluded that ginger is an effective means for reducing postoperative nausea and vomiting.

Vertigo
1 gram of powdered root daily
Ginger has been shown to be effective at reducing symptoms.

One gram of powdered  (Zingiber officinale) root in a single application has been reported to significantly reduce symptoms of artificially induced vertigo in one double-blind trial. In a double-blind trial, 1 gram of powdered ginger root was found to have very little effect in reducing vertigo related to seasickness.

HIV and AIDS Support (Asian Ginseng, Bupleurum, Cassia Bark, Chinese Scullcap, Jujube, Licorice, Peony, Pinellia)
Refer to label instructions
The herbal formula sho-saiko-to has been shown to have beneficial immune effects on white blood cells in people infected with HIV.

The Chinese herb bupleurum, as part of the herbal formula sho-saiko-to, has been shown to have beneficial immune effects on white blood cells taken from people infected with HIV. Sho-saiko-to has also been shown to improve the efficacy of the anti-HIV drug lamivudine in the test tube. One preliminary study found that 7 of 13 people with HIV given sho-saiko-to had improvements in immune function. Double-blind trials are needed to determine whether bupleurum or sho-saiko-to might benefit people with HIV infection or AIDS. Other herbs in sho-saiko-to have also been shown to have anti-HIV activity in the test tube, most notably Asian scullcap. Therefore studies on sho-saiko-to cannot be taken to mean that bupleurum is the only active herb involved. The other ingredients are peony root, pinellia root, cassia bark, root, jujube fruit, Asian ginseng root, Asian scullcap root, and licorice root.
