Common Name(s): Goshajinkigan , Gosha-jinki-gan , GJG
The medical literature primarily documents the use of gosha-jinki-gan (GJG) in treating overactive bladder and diabetes; however, data from quality clinical trials are lacking to support these uses.
Most clinical studies utilized a dosage range of 4.5 to 7.5 g/day.
GJG is composed of 10 crude traditional Japanese medicinal herbs; avoid use if hypersensitivity to any of the plant ingredients exists.
Avoid use during pregnancy and lactation.
GJG interacts with dioxins, melatonin, oxaliplatin, and paclitaxel.
In one study, patients reported mild adverse symptoms, including diarrhea, nausea, and urinary frequency. No abnormalities were recorded from hematology, biochemistry, and urinalysis results in another study.
A case report documented GJG causing interstitial pneumonia in an elderly patient.
GJG is composed of 10 crude drugs (see table) mixed with 19 parts lactose. 1

Traditional Japanese Kampo medicines utilize aqueous extracts of plant material mixtures. 2 , 3 Various formulations have been used for thousands of years to treat diseases and promote good health. Treatment is based on symptoms rather than disease, and the herbal medicine GJG has been prescribed for fatigue, cold extremities, leg numbness and pain, copious urine with thirst, lumbago, and geriatric cloudy vision. 3
Review of the medical literature documents limited specific chemical studies on GJG.
Uses and Pharmacology
The medical literature primarily documents the use of GJG in treating overactive bladder and diabetes.Bladder
GJG inhibited rhythmic bladder contractions in anesthetized dogs at 100 mg/kg. 4 Intravenous administration of GJG at 10 and 100 mg/kg inhibited urinary bladder contraction induced by pelvic nerve stimulation, and GJG 100 mg/kg inhibited acetylcholine-induced bladder contraction. 5
In rats, GJG increased voiding bladder capacity, voiding interval, micturition volume, and threshold pressure, and pretreatment with GJG partially blocked detrusor muscle overactivity induced by intravesical administration of acetic acid. 6 C-fiber activation of transmitter proteins and sensory receptors induced by acetic acid was reduced in rats pretreated with GJG. 7 GJG may also inhibit bladder activity by interacting with the autonomic nervous system. 8 GJG did not inhibit the amplitude of bladder contractions in rats, and the effect on urinary frequency is not associated with anticholinergic activity. The mechanism of action involves decreased bladder sensation through spinal kappa-opioid receptors, which are associated with delayed full bladder sensation and increased bladder capacity. 1Human data
Lower urinary tract symptoms (ie, flow and residual urine volume) improved 8 weeks after administration of GJG in 20 patients with prostatic disease. 9 Similar efficacy is documented in another study involving 25 patients treated with GJG, 10 with the mechanism of action involving activation of spinal kappa-opioid receptors leading to inhibition of the micturition reflex and inhibition of C-fiber activation of transmitter proteins and sensory receptors. In another clinical study of 30 patients, GJG improved similar lower urinary tract symptoms, as well as nocturia and urinary incontinence. 11 Although the details of the study could not be obtained, a clinical study of 704 patients treated with GJG 4.5 g/day for 1 year claimed improved symptoms of overactive bladder (ie, urge to urinate, daytime urinary frequency, nocturia, and urine leak) and quality of life. 12 A single treatment of GJG 7.5 g in 44 women documented improved symptoms of overactive bladder. 13Diabetes
In vitro and animal data
A study on experimental diabetes found that GJG 417 mg/kg/day (5 times the daily dose in humans) inhibited the decrease in glucose tolerance by cyproheptadine. Induced peripheral neuropathy in rats was reduced by a dosage of GJG 209 mg/kg/day (2.5 times the daily dose in humans). 14 The vasodilating effects of GJG improved peripheral circulation in diabetic rats through increased production of nitric oxide. 15 The increased concentrations of nitric oxide may be associated with GJG antinociceptive effects in diabetic rats. 16 A single dose of GJG improved insulin resistance and glucose utilization in diabetic rats, potentially through a physiological link via the nitric oxide pathway. 17 GJG improved insulin sensitivity with or without exogenous insulin in diabetic rats, potentially by correcting abnormal insulin signaling in skeletal muscle. 18 Treatment with GJG in diabetic rats reduced nitroxidative stress and lipid peroxidation in the retina, and improved glucose metabolism within the cells. 19 Hypertriglyceridemia induced by consuming a sucrose-rich diet was reduced in rats administered GJG. 20Human data
A 1-month clinical study examined the effects of GJG 7.5 g/day on insulin resistance in 71 patients with type 2 diabetes. At the end of the study, GJG reduced total cholesterol and triglyceride levels and improved insulin resistance. 21 , 22 A clinical study documents how GJG may improve ocular surface disorders, such as corneal sensitivity, superficial punctuate keratopathy (ie, irritation of cornea), and tear production in patients with insulin-dependent diabetes mellitus. 23 GJG may also improve visual disturbance due to cataracts. 24 A small study of 13 patients with diabetic neuropathy treated with GJG 7.5 g/day reported improved vibration sensation and relief from subjective symptoms, such as numbness and cold sensation. 25Other pharmacologic uses
GJG reduced trabecular bone loss and improved bone microstructure as assessed by microcomputed tomography in ovariectomized rats. 26Lower back pain
GJG may reduce lymphedema secondary to surgical procedures. 30Male infertility
In a trial of 38 patients treated with GJG 30 mg/kg 3 times a day for 12 consecutive weeks, GJG reduced painful muscle cramps associated with hepatic cirrhosis. 33
GJG is composed of 10 crude traditional Japanese medicinal herbs; therefore, avoid use if hypersensitivity to any of the plant ingredients exists.
Avoid use during pregnancy and lactation.
InteractionsDioxins and related organochlorine compounds
A Kampo formula containing GJG significantly improved respiratory symptoms caused by dioxins. 34Melatonin
Diurnal plasma melatonin was reduced in patients treated with GJG. 35Oxaliplatin
Peripheral and sensory neurotoxicity are major adverse effects related to oxaliplatin therapy. The symptoms include paresthesia and dysestheia of the extremities induced by cold exposure. Three clinical studies document that coadministration of GJG with oxaliplatin reduced the neurotoxicity in patients with colorectal cancer. Two mechanisms have been proposed: GJG promotes release of dynorphin, which helps improve numbness and pallesthesia through the opiate system; GJG enhances nitric oxide production, improving circulation and blood supply to the nerves. 36 , 37 , 38Paclitaxel
In one study, patients reported mild adverse symptoms, including diarrhea, nausea, and urinary frequency. 11 In another study, no abnormalities were recorded from hematology, biochemistry, and urinalysis results. 28
A case report documents GJG as causing drug-induced interstitial pneumonia in an elderly patient. 41
