• Asthma. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adults with allergic asthma shows that drinking one cup of tea prepared with multiple ingredients, including anise, twice daily for 6 months reduces sleep discomfort, cough frequency, and cough intensity when compared with placebo (19056). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Constipation. Oral anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A very small crossover trial in patients with constipation shows that taking an herbal tea containing a combination of anise, fennel, elderberry, and senna daily for 5 days can decrease colon transit time, increase the number of daily evacuations, and improve the perception of bowel function when compared with placebo (49494). It is unclear if these findings are due to anise, other ingredients, or the combination.
• Depression. It is unclear if oral anise oil is beneficial in patients with depression. Details: A small clinical study in adults with mild to moderate depression and irritable bowel syndrome (IBS) shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks improves symptoms of depression by an additional 28% when compared with placebo and an additional 32% when compared with peppermint (94947).
• Diabetes. It is unclear if oral anise seed powder is beneficial in patients with diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking anise seed powder 5 grams daily for 60 days decreases fasting blood glucose levels by 36%, total cholesterol levels by 7.5%, and triglyceride levels by 15% when compared to baseline. Fasting blood glucose significantly increased in the control group, and total cholesterol and triglyceride levels were relatively unchanged (94953).
• Dysmenorrhea. Although there has been interest in using oral anise for dysmenorrhea, there is insufficient reliable information about the clinical effects of anise for this purpose.
• Dyspepsia. It is unclear if oral anise powder is beneficial in patients with dyspepsia. Details: A small clinical study in adults with postprandial distress syndrome shows that taking anise powder 3 grams three times daily for 4 weeks improves quality of life and symptoms of functional dyspepsia when compared with placebo. Of the evaluated symptoms, improvement was seen in all categories when compared to placebo except for nausea and vomiting, which were present in less than 5% of patients at baseline (94944,94945).
• Irritable bowel syndrome (IBS). It is unclear if oral anise oil is beneficial inpatients with IBS. Details: A small clinical study in adults with IBS shows that taking enteric-coated anise oil 200 mg three times daily for 4 weeks eliminates IBS symptoms in 75% of patients, compared with 53% of patients taking peppermint oil and 35% taking placebo. The greatest symptom improvement occurred with abdominal pain, bloating, and reflux, and was maintained for an additional 2 weeks after treatment completion (94946).
• Lactation. It is unclear if oral anise tea is beneficial for increasing human milk production. Details: A moderate-sized clinical study in post-partum adults shows that drinking a tea containing anise 2 grams and black tea 1 gram 3 times daily with meals for 7 days increases the volume of pumped human milk on day 7 by an average of 98 mL and 113 mL, respectively, when compared with a placebo of black tea 3 grams daily and when compared with a control group not assigned to any tea or galactagogues (112863).
• Lice. Topical anise has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children 6-14 years of age shows that application of a topical spray containing anise oil, coconut oil, and ylang ylang oil three times at 5-day intervals is 92% effective for the treatment of head lice and seems to be comparable in effectiveness to a spray containing permethrin, malathion, piperonyl butoxide, and isododecane (13483).
• Menopausal symptoms. It is unclear if oral anise seed extract is beneficial in patients with menopausal symptoms. Details: A small clinical study in postmenopausal adults shows that taking anise seed extract 330 mg three times daily for 4 weeks reduces the frequency and severity of hot flashes by approximately 75% when compared with placebo (94948).
• Migraine headache. It is unclear if topical anise essential oil is beneficial in patients with migraine headache. Details: A small clinical study in adults with migraine headache shows that applying 2 mL of a cream containing anise essential oil 7% to the temporal and forehead zones at the onset of a migraine reduces the impact of the headache by approximately 10% when compared with a control cream. However, there was no effect of the anise cream on analgesic use or average headache severity when compared with placebo cream. Additionally, due to the strong smell of the anise cream, patient blinding may have been compromised (100166).
• Premenstrual syndrome (PMS). It is unclear if oral anise extract is beneficial in patients with PMS. Details: A small clinical study in female college students with PMS shows that taking anise extract 110 mg three times daily, starting 7 days before menstruation and ending 3 days after, improves concentration, mood, irritability, sleep, food cravings, and other symptoms of PMS, as measured using the Premenstrual Symptoms Screening Tool, when compared with placebo (103875). More evidence is needed to rate anise 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.
