• Age-related macular degeneration (AMD). It is unclear if oral goji berry reduces the risk of developing AMD. Details: A small, unblinded clinical study in healthy adults aged 45 to 65 years shows that consuming goji berries 28 grams five times a week for 90 days improves macular pigment optical density, which is a marker for AMD, when compared to baseline (110767). The validity of this finding is limited by the lack of statistical comparison to the other study group that received a supplement containing lutein and zeaxanthin.
• Cancer. Although there is interest in using oral goji for cancer, there is insufficient reliable information about the clinical effects of goji for this condition.
• Cardiovascular disease (CVD). It is unclear if oral goji improves risk factors for CVD. Details: A meta-analysis of 6 mostly small clinical studies of adults in China shows that consuming goji as polysaccharide extract or juice for 1-3 months modestly improves triglycerides, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and fasting blood glucose but does not impact total cholesterol when compared with no treatment or placebo (110765). Another meta-analysis of 4 small clinical studies in adults also shows that consuming goji polysaccharide extract or goji berries for 1-4 months modestly improves triglycerides and HDL but does not impact total or LDL cholesterol when compared with placebo or healthy eating. Goji also had no impact on systolic or diastolic blood pressure, or markers of oxidative stress (110768). However, the interpretation of the findings from these meta-analyses is limited by the use of variable goji forms and doses, as well as inclusion of studies in heterogeneous patients, including healthy people, patients with diabetes, and patients with metabolic syndrome. Furthermore, most studies were conducted in China; it is unclear if these benefits can be extrapolated to other geographic locations.
• Cognitive function. It is unclear if oral goji berry improves cognition in healthy young individuals. Details: A small clinical crossover study in healthy participants 14-24 years of age shows that taking goji berry fruit water extract (BIOMIX Company) 3600 mg in 3 divided doses daily for 4 weeks might improve certain cognitive measures such as verbal learning, short-term memory, and attention when compared with baseline (105488). The validity of these findings are limited due to incomplete outcome reporting and a lack of statistical comparisons between the treatment and placebo groups.
• Cough. Although there is interest in using oral goji for cough, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Depression. It is unclear if oral goji berry polysaccharide is beneficial for adolescents with subthreshold depression. Details: A small clinical study in adolescents aged approximately 15 years with subthreshold depression in China shows that taking goji berry polysaccharide extract 300 mg daily for 6 weeks modestly improves clinician-assessed depression scores (i.e. Hamilton Depression Scale, HAMD-24) but does not improve self-reported depression scores (i.e. Beck Depression Inventory) or scores assessing sleep quality, psychological distress, or anxiety when compared with placebo (110769). However, these results are from an interim analysis, which limits the interpretation of these findings. Furthermore, it is unclear if results can be extrapolated to patients in other geographic locations.
• Diabetes. It is unclear if oral goji berry polysaccharides improve glycemic control in patients with diabetes. Details: One small clinical study in patients with type 2 diabetes shows that taking goji fruit polysaccharide powder 150 mg twice daily for 3 months results in a slightly lower postprandial glucose area under the curve (AUC), but does not seem to affect insulin levels or insulin resistance, when compared with placebo. A subgroup of patients who were not taking antidiabetes medications had a greater reduction in postprandial blood glucose (92117).
• Dry eye. Although there is interest in using oral goji for dry eye, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Erectile dysfunction (ED). Although there is interest in using oral goji for ED, there is insufficient reliable information about the clinical effects of goji for this condition.
• Hypertension. Although there is interest in using oral goji root bark for hypertension, there is insufficient reliable information about the clinical effects of goji for this condition.
• Obesity. It is unclear if oral goji berry juice improves weight loss. Details: Preliminary clinical research in healthy, overweight adults shows that drinking a specific goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14 days while following a weight loss diet and participating in an exercise program decreases waist circumference by about 4.7 cm more than exercise and diet alone. However, drinking goji berry juice along with diet and exercise does not improve body weight, body mass index, or body fat when compared with diet and exercise alone (52536).
• Quality of life. Small clinical studies suggest that oral goji berry juice may modestly improve quality of life in healthy adults. Details: Small clinical studies in healthy adults suggest that taking a specific standardized goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14-30 days improves subjective measures of energy levels, athletic performance, sleep quality, mental acuity, calmness, feelings of well-being, and gastrointestinal regularity when compared with placebo (17082,52532,52542). These studies were funded by the juice manufacturer.
• Sunburn. It is unclear if oral goji extract can prevent sunburn. Details: A small clinical study in healthy Japanese adults shows that taking goji extract 900 mg daily for 8 weeks reduces and accelerates resolution of erythema after exposure to a standard dose of UVB irradiation when compared with placebo (110770). All study participants were highly UV-sensitive; it is unclear whether these results can be extrapolated to individuals less sensitive to UV irradiation.
• Tinnitus. Although there is interest in using oral goji for tinnitus, there is insufficient reliable information about the clinical effects of goji for this purpose. More evidence is needed to rate goji for these uses.

POSSIBLY EFFECTIVE

• Menopausal symptoms. Several clinical studies suggest that oral royal jelly, taken alone or in combination with other ingredients, modestly improves menopausal symptoms. It is unclear if topical royal jelly is beneficial for this use. Details: One clinical study in postmenopausal patients shows that taking royal jelly 1000 mg daily for 8 weeks reduces menopausal symptom scores by around 30% when compared with placebo (102527). Other small clinical studies show that taking one to two capsules of a specific combination product containing royal jelly and flower pollen (Melbrosia) daily for 12 weeks reduces menopausal symptoms and improves feelings of well-being when compared with baseline or placebo (18064,71956,72005). Another clinical trial in postmenopausal patients shows that taking two capsules of a specific combination product containing royal jelly, evening primrose oil, damiana, and ginseng (Lady 4) daily for 4 weeks decreases self-rated menopausal symptoms when compared with placebo (21003). Topical royal jelly has also been evaluated. A small clinical study in postmenopausal adults shows that applying vaginal cream containing royal jelly 15% daily for 12 weeks improves quality of life, sexual problems, and urinary problems similarly to vaginal estrogen cream 0.625 mg. However, estrogen cream improves vaginal atrophy better than royal jelly (92884).

POSSIBLY INEFFECTIVE

• Allergic rhinitis (hay fever). Oral royal jelly does not appear to prevent or treat symptoms of allergic rhinitis in children. Details: A clinical trial in children 5-16 years of age with allergic rhinitis shows that taking a specific royal jelly product (Bidro) 150 mg twice daily for 3-6 months before and during pollen season does not prevent or treat nasal congestion, sneezing, or eye discomfort when compared with placebo (71968).
• Diabetes. Oral royal jelly does not appear to improve glycemic control in patients with type 2 diabetes. Details: Most clinical research in patients with type 2 diabetes, along with a meta-analysis of five small clinical trials including patients with or without type 2 diabetes, shows that taking royal jelly 0.5-6 grams daily for 4-8 weeks does not improve markers of glycemic control such as fasting plasma glucose and glycated hemoglobin (HbA1c) (92879,92880,92881,102529).
• Physical performance. Oral royal jelly does not appear to improve physical performance in elderly nursing home residents. Details: A clinical trial in elderly nursing home residents shows that taking royal jelly 1.2 grams or 4.8 grams daily for one year does not improve hand grip strength, walking, or ability to stand on one leg when compared with placebo (95870).

• Androgenic alopecia. Although there has been interest in using topical royal jelly for androgenic alopecia, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Atherosclerosis. Although there has been interest in using oral royal jelly for atherosclerosis, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Athletic performance. Oral royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Two small clinical trials in elite male swimmers and runners show that taking royal jelly 400 mg and coenzyme Q10 60 mg daily for 10 days does not improve high-intensity interval training performance when compared with placebo (109992,109993). These studies were small and may not have been adequately powered to detect a difference between groups.
• Cancer-related fatigue. It is unclear if oral royal jelly is beneficial for improving cancer-related fatigue. Details: A small clinical study in patients with solid (nonhematologic) malignancies shows that taking 5 mL of processed honey and royal jelly twice daily for 4 weeks reduces fatigue when compared with 5 mL of honey alone (92877).
• Chemotherapy-induced acral erythema. It is unclear if oral royal jelly is beneficial for preventing acral erythema from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of acral erythema when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-induced hepatotoxicity. It is unclear if oral royal jelly is beneficial for preventing hepatotoxicity from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of hepatotoxicity when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-induced nephrotoxicity. It is unclear if oral royal jelly is beneficial for preventing chemotherapy-induced nephrotoxicity. Details: A small clinical study in patients receiving two cycles of cisplatin therapy shows that taking royal jelly capsules daily may attenuate increases in serum creatinine and urea levels when compared with placebo. However, it is unclear if this effect is clinically significant; the increased levels that occurred in the placebo group were still within normal limits (95871). The validity of these results is also limited by the short study duration and lack of statistical comparison between groups. Another small clinical trial in patients receiving tyrosine kinase inhibitor therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months does not reduce the risk of kidney dysfunction when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference between groups.
• Chemotherapy-related fatigue. It is unclear if oral royal jelly is beneficial for preventing fatigue from tyrosine kinase inhibitors (TKIs). Details: One small clinical trial in patients receiving TKI therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months reduces the frequency of chemotherapy-related fatigue when compared with placebo (105773,105774).
• Cognitive impairment. Oral royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in elderly patients with mild cognitive impairment shows that taking a specific combination product (Memo, Pharco Pharmaceuticals), which contains natural lyophilized royal jelly 750 mg, ginkgo leaf extract 120 mg, and Panax ginseng root extract 150 mg, daily for 4 weeks improves cognitive ability when compared with placebo (89712).
• Diabetic foot ulcers. Small clinical studies suggest that topical application of royal jelly plus panthenol may improve healing of diabetic foot ulcers. It is unclear if topical royal jelly alone is beneficial for this use. Details: One small clinical study shows that applying royal jelly 5% to a wound after conventional cleansing and debriding three times weekly for 3 months does not improve the healing of diabetic foot ulcers when compared with placebo (92882). However, other small clinical studies show that applying 1-3 grams of a specific combination ointment (Pedyphar) containing royal jelly and panthenol after conventional cleansing and debriding procedures twice weekly for up to 6 months may improve the healing of diabetic foot ulcers (71980,102526). In one of these studies, the rate of complete healing of life-threatening ulcers was 2.7-fold greater with this combination ointment when compared with panthenol alone (102526). Possible reasons for these discrepancies include the use of combination versus single ingredient ointments and the duration of treatment.
• Dry eye. It is unclear if oral royal jelly is beneficial in patients with dry eye. Details: A small clinical trial in Japanese patients with dry eye shows that taking enzyme-treated royal jelly 2.4 grams daily for 8 weeks does not improve tear stability or dry eye symptoms when compared with placebo (95869).
• Fractures. Although there has been interest in using oral royal jelly for healing of fractures, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Hepatitis. Although there has been interest in using oral royal jelly for hepatitis, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Male infertility. Intravaginal application of royal jelly has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in couples experiencing infertility due to asthenozoospermia shows that applying a saline solution containing royal jelly 3 grams, Egyptian bee honey 100 grams, and bee bread 1 teaspoon intravaginally before or after intercourse, starting one day after menstruation and continuing for 2 weeks, can increase the rate of pregnancy when compared with intrauterine insemination (55131). It is unclear if this effect is due to royal jelly, other ingredients, or the combination.
• Obesity. It is unclear if oral royal jelly is beneficial for reducing body weight in patients who are overweight or obese. Details: One small clinical study in overweight patients with type 2 diabetes shows that taking fresh royal jelly 1 gram daily for 8 weeks reduces body weight by around 2 kg and body mass index (BMI) by around 0.7 kg/m², as well as carbohydrate and total energy intake, when compared with placebo. However, the improvement is modest and may not be clinically significant (92878). Another small clinical study in overweight adults shows that taking royal jelly 1000 mg daily for 8 weeks does not reduce body weight, BMI, or appetite when compared with placebo (102528). However, this study may have been inadequately powered to detect a difference in these outcomes.
• Oral mucositis. It is unclear if oral royal jelly is beneficial for preventing or treating oral mucositis in patients receiving radiotherapy and/or chemotherapy. Details: One small clinical trial in patients receiving chemotherapy and radiotherapy shows that swishing and swallowing royal jelly 1 gram in two divided doses daily, in addition to standard rinses with benzydamine and nystatin, improves healing time of mild or moderate oral mucositis when compared with standard rinses alone (95867).
• Osteoporosis. It is unclear if oral royal jelly is beneficial in patients with osteoporosis. Details: A small clinical trial in postmenopausal adults shows that taking royal jelly powder 1000 mg, equivalent to 3000 mg of fresh royal jelly, daily for 6 months maintains bone mineral density (BMD) in the proximal femur and lumbar spine, while patients taking placebo saw significant reductions in lumbar spine BMD. Also, markers of bone turnover were significantly reduced with placebo, while significant changes in these markers were lacking in patients taking royal jelly (105775). It is unclear whether these findings can be generalized to patients with documented osteoporosis.
• Peptic ulcers. Although there has been interest in using oral royal jelly for peptic ulcers, there is insufficient reliable information about the clinical effects of royal jelly for this purpose.
• Premenstrual syndrome (PMS). It is unclear if oral royal jelly, taken alone or in combination with other ingredients, is beneficial in patients with PMS. Details: A small clinical study in healthy college students shows that taking royal jelly 1 gram daily starting on the first day of menstruation and continuing for two consecutive menstrual cycles improves PMS symptoms when compared with placebo (95873). However, methodological flaws associated with the study limit the validity of these results. A small clinical study shows that taking a specific combination product (Femal, Natumin Pharma), providing royal jelly 12 mg, bee pollen extract 72 mg, and bee pollen plus pistil extract 240 mg, twice daily over 2 menstrual cycles seems to decrease some symptoms of PMS including irritability, weight increases, and edema (12008). It is unclear if these effects are due to royal jelly, other ingredients, or the combination.
• Renal cell carcinoma. It is unclear if oral royal jelly is beneficial in patients with renal cell carcinoma. Details: One small clinical trial in patients receiving tyrosine kinase inhibitor (TKI) therapy for renal cell carcinoma shows that taking royal jelly 900 mg four times daily for 3 months reduces tumor size, improves chemotherapy-related fatigue and anorexia, and reduces the need for dose reduction or the discontinuation of therapy when compared with placebo (105773,105774). Royal jelly does not seem to reduce other TKI-related adverse effects, including gastrointestinal symptoms, oral mucositis, acral erythema, anemia, hepatotoxicity, or nephrotoxicity, when compared with placebo (105773). However, this study may have been inadequately powered to detect a difference in these outcomes. More evidence is needed to rate royal jelly for these uses.

POSSIBLY SAFE ...when goji fruit preparations are used orally and appropriately, short-term. Goji berry whole fruit, boiled or steamed, has been used with apparent safety at a dose of 15 grams daily for 16 weeks (105489). Other goji berry products have also been used with apparent safety in clinical research, including a specific goji fruit juice (GoChi, FreeLife International) 120 mL daily for 30 days (52532), a goji fruit polysaccharide 300 mg daily for 3 months (92117), and a specific milk-based formulation of goji berry (Lacto-Wolfberry, Nestlé Research Center) for 3 months (52539). There has been some concern about the atropine content of goji; however, most analyses show that levels of atropine in goji berries from China and Thailand are far below potentially toxic levels (52524,94667). There is insufficient reliable information available about the safety of oral use of other parts of the goji plant.

Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.  Details Fo-ti has been linked to liver damage in many reports (7626,7627,14327,14339,14347,14482,16459,17192,50711,50727,50729,92892,92895).

STIMULANT LAXATIVES Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of fluid and electrolyte depletion when taken with stimulant laxatives.  Details Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects (5,16459). However, in vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root (99855).

SULINDAC (Clinoril) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, fo-ti might increase or decrease the levels and clinical effects of sulindac.  Details Animal research suggests that the type of fo-ti extract might affect the levels of sulindac differently; the raw plant may increase levels, but processed parts may decrease levels (112351). Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, fo-ti might increase the effects and adverse effects of warfarin.  Details Fo-ti may have stimulant laxative effects and cause diarrhea, especially when the raw or unprocessed fo-ti root is used (5,12,16459,50733,99855). Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Also, fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of warfarin. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery (17192).

ANTIDIABETES DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.  Details Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects (7126,92118,94667). However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia (92117).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.  Details Animal and in vitro research suggest that goji root bark has hypotensive effects (7126,94667). However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans (17082).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes (105486). Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate (7158,105462). Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.  Details In vitro research shows that goji berry juice inhibits CYP2D6 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.  Details In vitro research shows that goji berry juice inhibits CYP3A4 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.

FLECAINIDE (Tambocor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might increase the levels and clinical effects of flecainide.  Details In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide (105462).

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Goji can increase the effects of warfarin and possibly increase the risk of bleeding.  Details There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine (7158,16529,23896,105462,105487). Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9) (7158).

General ...Orally, fo-ti may be unsafe.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, nausea, and vomiting with use of unprocessed fo-ti.
Serious Adverse Effects (Rare):
Orally: Hepatotoxicity with processed or unprocessed fo-ti.

Dermatologic ...Orally, one case of a fine maculopapular rash was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if the rash was due to fo-ti or other ingredients in the herbal product.

Gastrointestinal ...Orally, unprocessed fo-ti may cause diarrhea, abdominal pain, nausea, and vomiting (12,50733).

Hematologic ...Orally, one case of mild eosinophilia was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if this reaction was due to fo-ti or other ingredients in the herbal product. A case of agranulocytosis was reported in a 65-year-old female taking fo-ti 30 grams/day for 17 days. The patient recovered gradually following a 15-day hospitalization, which included treatment with intravenous steroids and granulocyte colony-stimulating factor (112231).

Hepatic ...Orally, cases of liver damage due to both processed and unprocessed fo-ti have been well documented in the medical literature. (7626,7627,14327,14339,14347,14482,16459,17192,50711,50726)(50727,50729,92892,92895,112231).
In a systematic review, around 450 cases of hepatitis associated with fo-ti were identified. These cases occurred in patients 5-78 years of age. Liver damage occurred at a wide range of doses, formulations, and durations of intake. The type of liver injury ranged from hepatocellular, to cholestatic, or mixed. Outcomes ranged from full recovery to cirrhosis, liver transplantation, and/or death. The evidence suggests that when the daily fo-ti dose is less than 12 grams, the median time to occurrence of liver damage is 60 days. When the daily fo-ti dose is more than 12 grams, the median time to liver damage is 30 days (92895). Presenting signs and symptoms may include jaundice, abdominal pain, nausea, fatigue, loss of appetite, dark urine, myalgias, and elevations in liver function tests (LFTs), ferritin, transferrin, prothrombin time, and INR (17192,92892). Other manifestations may include fever, skin rash, thrombocytopenia, pancytopenia, and arthralgias. Symptoms and increased LFTs usually seem to resolve within a month after discontinuing fo-ti (7626,7627,14339,14347,14482,16459). In one case series, liver enzymes began to normalize 48 hours after discontinuation of fo-ti and treatment with S-adenosylmethionine, compound glycyrrhizin injection, polyene phosphatidylcholine, and reduced glutathione. All patients were eventually discharged home in stable condition (92892). Rechallenge with fo-ti should not be attempted. A patient who had recovered from hepatitis associated with fo-ti use presented with myalgias and markedly elevated LFTs after a single dose of the herb (17192).
It is thought that this idiosyncratic reaction leading to liver damage is at least partially related to genetic polymorphisms. Cytochrome P450 1A2 (CYP1A2) is the predominant enzyme involved in biotransformation of emodin, a constituent of fo-ti thought to play a role in liver damage. In one genetic study, the frequency of CYP1A2*1C mutation in fo-ti induced drug-induced liver injury patients was 46.5%, which is significantly higher than the 27.9% frequency of liver injury reported in healthy patients without the mutation. Patients with a CYP1A2*1C mutation may have decreased activity of the CYP1A2 enzyme, which could inhibit the metabolism of fo-ti, causing an accumulation of toxic substances (92897).

General ...Orally, goji fruit seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions including anaphylaxis.

Dermatologic ...A case of photosensitivity secondary to consumption of goji berries has been reported. The patient presented with a pruriginous eruption that had lasted for 2 weeks. The patient had been taking goji berries for 5 months and cat's claw for 3 months. Upon testing, it was revealed that the patient tested positive to goji berries in a photoprovocation test, but not to cat's claw (40263).

Hepatic ...Orally, consumption of goji berries has been associated with a single case report of autoimmune hepatitis (52541). A case of acute hepatitis has also been reported in a female who consumed 2 ounces of a specific combination product (Euforia, Nuverus International) containing goji berry, pomegranate, curcumin, green tea, noni, acai berry, aloe vera, blueberry, resveratrol, mangosteen, and black seed, daily for one month. It is unclear whether the liver injury was caused by goji berry, other ingredients, or the combination (90125).

Immunologic ...Several cases of allergic reactions secondary to consumption of goji berries have been reported. Symptoms included facial angioedema with dyspnea, pharyngeal itching, itching in the mouth, ears, and axilla, labial angioedema, and perioral skin rash (92116). Anaphylaxis has also been reported (52538).

General ...Orally and topically, royal jelly seems to be well tolerated.
Most Common Adverse Effects:
Orally: Dyspnea, eczema, oral allergy syndrome, pruritus, and urticaria in people with a history of asthma or atopy.
Topically: Contact dermatitis and skin irritation.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis, status asthmaticus, and death in people with a history of asthma or atopy.

Gastrointestinal ...There is one case report of hemorrhagic colitis with abdominal pain, bloody diarrhea with concomitant hemorrhagic and edematous mucosa of the sigmoid colon after ingestion of royal jelly. Symptoms resolved within 2 weeks following discontinuation of royal jelly and conservative treatment (3516).

Immunologic ...In people with a history of atopy or asthma, royal jelly taken orally appears to cause a high rate of allergic symptoms including pruritus, urticaria, eczema, eyelid and facial edema, conjunctivitis, rhinorrhea, dyspnea, oral allergy syndrome, and asthma (7314,7315,7316,10623,95872). In severe cases, royal jelly can cause status asthmaticus, anaphylaxis, and death (792,7315,7316,10623,10624,108511). Allergic symptoms are associated with IgE-mediated hypersensitivity reactions (3513,10623).
Topically, skin irritation, exacerbation of dermatitis, or contact dermatitis may occur (791).
From occupational exposure, royal jelly can cause allergic rhinoconjunctivitis and asthma (95868).
