Inclusion
- Meet Rome III criteria for IBS.
- Willing and able to provide written informed consent.
- If a female of childbearing potential, must be using an acceptable form of contraception during the study and for 30 days after the last dose. Acceptable methods include surgical sterilization, hormonal contraceptives (such as oral contraceptives, Depo-Provera, NuvaRing), condoms used with a spermicide, an IUD \[Intrauterine device\] or abstinence.

- Aged 18 to 65 years, inclusive.
- Have a body mass index (BMI) between 18 and 40 kg/m2, inclusive.
- Have a negative urine drug screening at Visit 1.
- Have normal or not clinically significant laboratory results as reviewed by the study physicians.
- Have a normal rectal examination result on file within the past 2 years or performed at Visit 1 in order to exclude the possibility of an evacuation disorder (examination must exclude findings suggestive of an evacuation disorder such as high sphincter tone at rest, failure of perineal descent and spasm, tenderness or paradoxical contraction of the puborectalis muscles).
- Agree to avoid alcohol during the entire study to avoid corrupting the data from the rectal barostat tests.
Exclusion
- Have a structural or metabolic diseases or conditions that affect the GI system.
- Be taking any medication that in the opinion of the principal investigator has a potential to alter GI transit (this includes but is not limited to osmotic or stimulant laxatives, magnesium or aluminum-containing antacids, prokinetics, erythromycin, gabapentin, pregabalin, narcotics, anticholinergics, antidepressants \[including selective norepinephrine reuptake inhibitors\], antipsychotics, opiates, GABAergic agents and benzodiazepines).
- Note: Tricyclic antidepressants are permissible at doses equal to or less than 25 mg daily; selective serotonin reuptake inhibitor antidepressants are permissible at low, stable doses. Analgesics such as Tylenol, ibuprofen, naproxen and aspirin are not permissible during Visits 2 and 3 to avoid corrupting data from the rectal barostat tests. All medications will be reviewed by the principal investigator on a case by case basis.
- Rescue medications: Rescue medications will be reviewed and approved as necessary for exacerbation of constipation or diarrhea since the study medication treatment period is about 14 days total. The patient will contact the study staff to request review and approval of the use of a rescue medication by the principal investigator. The use of the rescue medication will be documented by the patient in the bowel pattern, bloating and pain diary. Rescue medications are not allowed within 7 days of the rectal sensation studies to ensure data integrity.
- Have clinical evidence, including but not limited to, of a clinically significant abnormal physical examination or laboratory value or of a past event documented in the past medical record, or current clinically significant abnormal physical examination or laboratory value that could indicate significant cardiovascular, respiratory, renal, hepatic, GI, hematological, neurological, psychiatric or other diseases that interfere with the objectives of the study. If a laboratory test value falls outside of the reference range and is considered clinically significant, it may be repeated once at the discretion of the principal investigator. If the laboratory test result remains abnormal and clinically significant, the patient will be discontinued from the study and referred to a primary care physician for evaluation.
- Be a known substance abuser or be considered to be an alcoholic not in remission.
- Have participated in another clinical study in the past 30 days.
- Have a history of allergic reactions to egg, ginseng, ginger or Sichuan pepper.
