• Dyslipidemia. Oral Indian gooseberry seems to be beneficial for dyslipidemia. Details: Meta-analyses of 12 small clinical studies in healthy adults or patients with dyslipidemia, diabetes, hypertension, or metabolic syndrome show that taking Indian gooseberry fruit extract or powder 0.5-3 grams daily or Indian gooseberry fruit 12 grams daily for 2-12 weeks reduces total cholesterol by around 39 mg/dL, low-density lipoprotein (LDL) cholesterol by around 15-34 mg/dL, and triglycerides by around 22-52 mg/dL when compared with control groups. Results are conflicting whether Indian gooseberry increases high-density lipoprotein (HDL) cholesterol (111567,111568). Subgroup analysis suggests that Indian gooseberry is more effective at doses greater than 1 gram daily and in adults with triglycerides above 150 mg/dL (111568). Clinical research in patients with dyslipidemia shows that taking Indian gooseberry whole fruit extract (Tri-low, Arjuna Natural Ltd.) 500 mg twice daily for 12 weeks reduces triglyceride and low-density lipoprotein (LDL) cholesterol levels by 34% and 20%, respectively, compared with 15% and 5%, respectively, in patients taking placebo (99238).
• Gastroesophageal reflux disease (GERD). Oral Indian gooseberry seems to be beneficial for reducing symptoms of GERD. Details: Clinical research in adults who have had non-erosive symptoms of GERD for at least 3 months shows that taking Indian gooseberry fruit extract 1000 mg twice daily for 4 weeks reduces the frequency and severity of heartburn and regurgitation by about 63% and 50%, respectively, compared with reductions of 24% and 5%, respectively, in patients taking placebo (99240).

• Aging skin. Oral Indian gooseberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in healthy, middle-aged females shows that drinking 50 mL of a juice containing Indian gooseberry extract 30-60 mg and lingonberry extract 25-50 mg daily for 12 weeks improves skin elasticity, thickness, wrinkles, and hydration when compared with placebo (102856). It is unclear if these effects are due to Indian gooseberry, lingonberry, or the combination. Another small clinical study in healthy, middle-aged females shows that applying a topical emulsion containing extracts of Indian gooseberry 3% and gotu kola 3% twice daily for 60 days improves skin hydration, some measures of skin wrinkles, and elasticity of the cheek but not the eye when compared with placebo (111571). It is unclear if these effects are due to Indian gooseberry, gotu kola, or the combination.
• Androgenic alopecia. Topical Indian gooseberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In individuals with self-perceived hair loss, preliminary clinical research shows that applying a hair product containing Indian gooseberry modestly improves hair growth rate and density, as well as hair thinning, when compared with baseline. Patients used a leave-in product containing Indian gooseberry (Saberry), coconut water solids (Cococin), gamma-L-glutamyl-selenomethionine (Peptiselect), and other ingredients as 3.5 mL in females and 2 mL in males, once daily for 3 months (105353).
• Cancer. Although there is interest in using oral Indian gooseberry for cancer, there is insufficient reliable information about the clinical effects of Indian gooseberry for this purpose.
• Cardiovascular disease (CVD). It is unclear if oral Indian gooseberry is beneficial for the prevention of CVD. Details: A meta-analysis of 9 small clinical studies in adults who are healthy or have CVD risk factors shows that taking Indian gooseberry fruit extract or powder 500-1500 mg daily for 2-12 weeks reduces low-density lipoprotein (LDL) cholesterol by around 15 mg/dL, very low-density lipoprotein (VLDL) cholesterol by around 5 mg/dL, triglycerides by around 22 mg/dL, and high-sensitivity C-reactive protein when compared with control groups. However, the meta-analysis suggests that Indian gooseberry does not improve high-density lipoprotein (HDL) cholesterol, systolic blood pressure, or diastolic blood pressure (111567). The validity of these findings is limited by small sample sizes and considerable heterogeneity among the included studies.
• Coronavirus disease 2019 (COVID-19). It is unclear if oral Indian gooseberry is beneficial for the treatment of COVID-19 in hospitalized adults. Details: A small clinical trial in adults hospitalized with COVID-19 shows that receiving Indian gooseberry powder 2 grams twice daily for 10 days does not impact RT-PCR positivity rate at day 10 when compared with placebo. Additionally, there were no clear trends in clinical improvement in patients receiving Indian gooseberry when compared with placebo. All patients in this study also received oral hydroxychloroquine and lopinavir/ritonavir (110012).
• Diabetes. Several small or limited-quality clinical studies suggest that oral Indian gooseberry may modestly improve glycemic control and blood lipid levels in patients with type 2 diabetes. Details: A moderate-sized, open-label study in adults with newly-diagnosed type 2 diabetes and dyslipidemia shows that taking Indian gooseberry extract, standardized to 10% beta-glucogallin, 2 grams daily for 90 days reduces glycated hemoglobin (HbA1c), fasting blood glucose, and postprandial blood glucose when compared to baseline, with superior effects on fasting blood glucose and postprandial blood glucose when compared with metformin 500 mg (111569). A smaller clinical study in patients with type 2 diabetes on stable doses of metformin shows that taking Indian gooseberry fruit extract (Capros, Natreon Inc) 500 mg twice daily for 12 weeks reduces HbA1c by around 0.5% and improves low-density lipoprotein (LDL) cholesterol, triglyceride, and high-density lipoprotein (HDL) levels when compared with placebo. Taking a lower dose, 250 mg twice daily, does not seem to improve HbA1c but has a modest effect on lipid levels (105356). Another small clinical study in patients with type 2 diabetes using various antidiabetes drugs shows that taking powdered Indian gooseberry fruit 1 gram, 2 grams, or 3 grams daily for 3 weeks modestly reduces fasting and 2-hour postprandial blood glucose levels and improves lipid levels when compared to baseline (105355). The validity of these findings is limited by the lack of a comparator group.
• Hangover. It is unclear if oral Indian gooseberry is beneficial for hangover prevention. Details: A small clinical trial shows that taking Indian gooseberry leaf extract (Phyllpro) 750 mg daily for 10 days prior to alcohol intoxication modestly reduces some hangover symptoms 10 hours later, including nausea, headache, lack of appetite, and dizziness, when compared with placebo. Blood alcohol levels after 12 hours were also reduced. However, the overall hangover score was not significantly different between groups (99846).
• Hepatitis B. Although there is interest in using oral Indian gooseberry for hepatitis B, there is insufficient reliable information about the clinical effects of Indian gooseberry for this condition.
• Hypercholesterolemia. Small studies suggest that oral Indian gooseberry might help to reduce low-density lipoprotein (LDL) cholesterol levels. Details: Preliminary clinical research shows that taking Indian gooseberry might reduce levels of LDL cholesterol in patients with hypercholesterolemia. One preliminary clinical study shows that taking Indian gooseberry 50 grams for 4 weeks decreases LDL cholesterol by 15% when compared to baseline (2077). Other preliminary clinical research shows that taking Indian gooseberry fruit extract (Amlamax, Arjuna Natural Ltd.) 500 mg or 1000 mg daily for 6 months reduces levels of LDL cholesterol by about 13% when compared with baseline (99241). Also, one small study shows that taking an Indian gooseberry fruit juice powder 500 mg daily for 6 weeks modestly decreases LDL cholesterol and triglyceride levels when compared with baseline (99242). Some preliminary clinical research also shows that Indian gooseberry reduces LDL cholesterol in obese individuals. One small study shows that taking Indian gooseberry fruit extract (Capros, Natreon Inc.) 500 mg twice daily for 12 weeks reduces LDL cholesterol by 16 mg/dL in this population when compared to baseline (92515). However, the validity of these studies is limited by the lack of comparator groups.
• Hypertension. It is unclear if oral Indian gooseberry is beneficial for hypertension. Details: In patients with uncontrolled hypertension using standard therapies, clinical research shows that taking Indian gooseberry dried fruit powder 500 mg three times daily for 8 weeks reduces systolic blood pressure (SBP) and diastolic blood pressure (DBP) by 16% and 12%, respectively, from baseline, which is significantly greater than reductions seen with placebo. The frequency of response to treatment, based on a reduction in SBP or DBP of at least 10 mmHg or 5 mmHg, respectively, was also increased from up to 50% to at least 83% of patients (105352). However, other clinical research in adults with cardiovascular risk factors shows that taking Indian gooseberry 500-1500 mg twice daily for 2-12 weeks does not reduce SBP or DBP more than placebo (105354,111567).
• Irritable bowel syndrome (IBS). Indian gooseberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small, open-label study of adults with IBS shows that taking 7 grams of an Unani medicinal product called Jawarish Shahi, containing Indian gooseberry, terminalia, coriander, cardamom, and willow bark, twice daily for 45 days reduces the severity of IBS, as measured by improvements in abdominal pain and distension, bowel habits, and quality of life, when compared to baseline (111570). The validity of these findings is limited by insufficient blinding and the lack of a comparator group. It is unclear if these effects are due to Indian gooseberry, other ingredients, or the combination.
• Metabolic syndrome. It is unclear if oral Indian gooseberry is beneficial for metabolic syndrome. Details: Preliminary clinical research in adults with metabolic syndrome shows that taking a specific Indian gooseberry extract (Capros, Natreon Inc.) 250 mg twice daily for 12 weeks reduces total cholesterol by nearly 10%, low-density lipoprotein (LDL) cholesterol by 15%, and triglycerides by 10%, and increases high-density lipoprotein (HDL) cholesterol by about 7% when compared with placebo. Additionally, taking this product as 500 mg twice daily reduces total cholesterol by 14%, LDL cholesterol by 26%, and triglycerides by 19%, and increases HDL cholesterol by 22% when compared with placebo. Both doses also seem to improve markers of endothelial function, oxidative stress, and systemic inflammation (102857).
• Obesity. It is unclear if oral Indian gooseberry is beneficial for improving weight loss or metabolic parameters in adults with obesity. Details: Preliminary clinical research in overweight or obese individuals shows that taking Indian gooseberry fruit extract (Capros, Natreon Inc.) 500 mg twice daily for 12 weeks reduces low-density lipoprotein (LDL) cholesterol by 16 mg/dL when compared to baseline. However, there was no effect on other lipids or on blood pressure, body weight, or body mass index (92515). The validity of these findings is limited by the lack of a comparator group.
• Oral mucositis. It is unclear if oral Indian gooseberry is beneficial in patients with radiation-induced mucositis. Details: A retrospective observational study in patients with head and neck cancer receiving radiotherapy suggests that rinsing the mouth with Indian gooseberry 1% and povidone-iodine twice daily is associated with delayed development of mucositis and intolerable mucositis and a decreased incidence of intolerable mucositis when compared with povidone-iodine alone (111566). The validity of these findings is limited by the retrospective study design.
• Osteoarthritis. Oral Indian gooseberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with knee osteoarthritis suggests that specific Ayurvedic formulas containing Indian gooseberry may be equivalent to glucosamine sulfate 2 grams daily or celecoxib 200 mg daily for reducing pain. Two capsules containing Indian gooseberry 166.66 mg/capsule, ginger 33.33 mg/capsule, and Tinospora cordifolia 73.33 mg/capsule, with or without Boswellia serrata 100 mg/capsule, taken three times daily for 24 weeks, were used. All four treatments reduced active pain by about 28% to 38%, functional pain by 19% to 29%, and functional difficulty by 18% to 25%, with no significant between-group differences in the observed improvements (89557). It is not clear if these effects are due to Indian gooseberry, the other ingredients, or the combination.
• Periodontitis. It is unclear if subgingival Indian gooseberry is beneficial for periodontitis. Details: Clinical research in patients with chronic periodontitis shows that the subgingival application of a sustained-release Indian gooseberry fruit 10% gel following scaling and root planing does not affect plaque or gingivitis development over 2-3 months when compared with placebo. However, there was a modest benefit on periodontal destruction based on probing pocket depth (105358).
• Vitiligo. Oral Indian gooseberry has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with vitiligo shows that taking 1 tablet containing Indian gooseberry 100 mg, vitamin E 10 mg, and carotenoids 4.7 mg orally 3 times daily for 6 months, in combination with conventional topical therapy and/or phototherapy, increases re-pigmentation in the head, neck, and trunk and decreases signs of inflammation when compared with conventional treatment alone (92513). More evidence is needed to rate Indian gooseberry for these uses.

• Angina. It is unclear if oral Terminalia arjuna is beneficial in patients with angina. Details: Low-quality clinical research in patients with angina shows that taking Terminalia arjuna extract 500-2000 mg orally daily for 3 months reduces the frequency of angina symptoms by 50% to 71% when compared with baseline. These results were similar to taking conventional therapy (2502,2503). Other preliminary research in adults with chronic stable angina shows that taking Terminalia arjuna 500 mg orally three times daily for 7 days reduces the need for rescue treatment and improves exercise tolerance when compared with placebo. Improvements were similar to taking isosorbide mononitrate 20 mg twice daily (92833).
• Asthma. Although there has been interest in using oral Terminalia arjuna for asthma, there is insufficient reliable information about the clinical effects of Terminalia arjuna for this purpose.
• Athletic performance. It is unclear if oral Terminalia arjuna is beneficial for athletic performance. Details: A small clinical study in young regular exercising males shows that taking Terminalia arjuna extract (Oxyjun, Enovate Biolife Pvt Ltd, India) 400 mg daily for 8 weeks increases the time to exhaustion by approximately 117 seconds when compared with placebo. There were also modest improvements in feelings of perceived exertion and the left ventricular ejection fraction, a measure of blood pumped from the heart with each heartbeat (111093). It is unclear if oral Terminalia arjuna is beneficial other populations such as athletes and females.
• Coronary heart disease (CHD). It is unclear if oral Terminalia arjuna is beneficial in patients with CHD. Details: Preliminary clinical research in patients with CHD shows that taking Terminalia arjuna bark powder 500 mg orally daily for 30 days decreases levels of total cholesterol by about 10% and low-density lipoprotein (LDL) cholesterol by about 16% when compared with baseline. Taking Terminalia arjuna bark powder did not improve high-density lipoprotein (HDL) cholesterol levels (92832).
• Heart failure. The effects of Terminalia arjuna in patients with heart failure is unclear; evidence to date comes from small, short-term clinical studies, and results are conflicting. Details: Preliminary, low-quality clinical research in patients with severe, refractory congestive heart failure shows that taking Terminalia arjuna bark extract 500 mg orally three times daily for 2 weeks, as an adjunct to conventional therapy, improves left ventricular ejection fraction (LVEF) by 17% when compared with placebo (2504). However, other preliminary clinical research in adults with stage II heart failure shows that taking an extract of Terminalia arjuna bark 750 mg orally twice daily as an adjunct to conventional therapy for 12 weeks does not improve LVEF, functional class, or functional capacity when compared with placebo (96726). However, the validity of these trials is limited by short-term treatment and variation in the conventional therapies used to manage heart failure.
• Hyperlipidemia. It is unclear if oral Terminalia arjuna is beneficial for improving lipid levels. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors, such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days decreases levels of low-density lipoprotein (LDL) cholesterol and triglycerides by 17% and 35%, respectively, and increases high-density lipoprotein (HDL) cholesterol levels by 9%, when compared with baseline. Improvements in lipid parameters were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). However, this study may have been inadequately powered to detect a difference between groups.
• Hypertension. It is unclear if oral Terminalia arjuna is beneficial for reducing blood pressure. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days reduces systolic and diastolic blood pressure by 11% and 14%, respectively, when compared with baseline. Improvements in blood pressure were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). However, this study may have been inadequately powered to detect a difference between groups.
• Obesity. It is unclear if oral Terminalia arjuna is beneficial for weight loss. Details: Preliminary clinical research in patients with elevated cardiovascular risk factors, such as hypertension, dyslipidemia, or obesity, shows that taking Terminalia arjuna 5 grams orally twice daily for 60 days reduces body mass index (BMI) by 6% when compared with baseline. Improvements in BMI were similar to taking amlodipine 5 mg and atorvastatin 10 mg daily (109677). This study may have been inadequately powered to detect a difference between groups. More evidence is needed to rate Terminalia arjuna for these uses.
