• Breast cancer-related hot flashes. Oral chicory has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical study of breast cancer survivors who use estrogen deprivation therapy shows that taking 5 mL of chicory and fumitory syrup 3 times daily for 4 weeks significantly decreases the frequency and severity of hot flashes when compared with placebo. Hot flash frequency and severity were both reduced by around 57% in the treatment group, as compared with a 10% reduction in the placebo group (110724). The use of a per-protocol analysis limits the validity of these findings. Additionally, it is unclear if these findings are due to chicory, fumitory, or the combination. Cancer. Although there has been interest in using oral chicory for the treatment or prevention of cancer, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Constipation. Although there has been interest in using oral chicory for constipation, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Diabetes. Although there has been interest in using oral chicory for diabetes, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Dyspepsia. Although there has been interest in using oral chicory for dyspepsia, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Hyperlipidemia. Although there has been interest in using oral chicory for hyperlipidemia, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Hypertension. Although there has been interest in using oral chicory for hypertension, there is insufficient reliable information about the clinical effects of chicory for this purpose.
• Neonatal jaundice. It is unclear if oral chicory solution is beneficial in neonates with jaundice. Details: A moderate-sized clinical study of nursing mothers shows that taking 50 mL of chicory 10% distillate every 12 hours for 3 days reduces bilirubin levels of breastfed neonates with jaundice by around 0.3 mg/dL when compared with placebo (110723). However, it is unlikely that these findings are clinically significant.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral chicory seed is beneficial in patients with NAFLD. Details: A small clinical trial in patients with NAFLD shows that taking chicory seed 9 grams infused in hot water daily for 12 weeks reduces body mass index (BMI) by 0.66 kg/m2 when compared with placebo. When combined with turmeric 3 grams daily, serum alkaline phosphatase was decreased. Although levels of other liver enzymes decreased when compared to baseline, changes were not significant when compared with placebo. Also, taking chicory seed did not affect plasma lipid levels (102350).
• Osteoarthritis. It is unclear if oral chicory root extract is beneficial in patients with osteoarthritis. Details: A small clinical study in patients with knee or hip osteoarthritis shows that taking chicory root extract 600 mg three times daily for 3 months does not improve pain, stiffness, or functional ability when compared with placebo (93647). However, this small study was likely underpowered to detect differences between groups. More evidence is needed to rate the effectiveness of chicory for these uses.

• Malaria. Although there has been interest in using oral gentian for malaria, there is insufficient reliable information about the clinical effects of gentian for this purpose.
• Obesity. It is unclear if oral gentian is beneficial for obesity. Details: Preliminary clinical research in healthy adults shows that consuming a pudding containing microencapsulated gentian root extract 1.25 g at breakfast modestly reduces caloric intake over 24 hours, but does not affect self-reported feelings of hunger or fullness, when compared with placebo pudding (96534).
• Rhinosinusitis. Oral gentian has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a specific combination product (SinuComp; Sinupret) that contains gentian root 6 mg , elderflower, verbena, cowslip flower, and sorrel improves the symptoms of acute or chronic sinusitis when compared with placebo (374,379). Observational research in adults with acute rhinosinusitis suggests that taking the same combination product orally three times daily, in addition to topical mometasone furoate nasal spray, for 7 days is associated with lower symptom scores when compared with mometasone nasal spray alone (95907).
• Wound healing. Although there has been interest in using topical gentian for wound healing, there is insufficient reliable information about the clinical effects of gentian for this purpose. More evidence is needed to rate gentian for these uses.

• Chronic venous insufficiency (CVI). Most clinical research suggests that oral horse chestnut extract reduces symptoms of CVI. Details: Clinical research shows that taking horse chestnut seed extract 300 mg twice daily or providing aescin, a constituent of horse chestnut, 50-75 mg twice daily for up to 12 weeks can reduce some symptoms of CVI, such as varicose veins, pain, tiredness, tension, itching, edema, and swelling in the legs (281,282,283,284,285,12113,55477,55481,55501,55502)(55520,55526,55537). However, some preliminary clinical research suggests that horse chestnut seed extract (Venostasin, Klinge Pharma GmbH) may be less effective than maritime pine bark (Pygnoforton, Plantorgan) for reducing leg swelling, cramps, and a feeling of heaviness in patients with CVI (7693).

• Irritable bowel syndrome (IBS). It is unclear if oral horse chestnut is beneficial for IBS. Details: A small, preliminary clinical trial and retrospective case series show that taking a combination product containing horse chestnut extract 470 mg, quebracho colorado 150 mg, and peppermint oil 0.2 mL (Atrantil, KBS Research, LLC) daily for 2 weeks reduces abdominal pain, constipation, and bloating when compared with baseline in patients with constipation-predominant IBS (95429,95430). The effects of horse chestnut alone are unclear.
• Kidney stones (nephrolithiasis). It is unclear if oral aescin, a constituent of horse chestnut, is beneficial for kidney stones. Details: A large clinical study in outpatient adults in Iraq with a single kidney stone shows that taking aescin, a constituent of horse chestnut, 120 mg daily for 10 days increases the rate of stone expulsion when compared with placebo, but not when compared with prednisolone 25 mg daily. Aescin also decreases the time to stone expulsion and increases the percent of patients experiencing complete pain relief when compared with prednisolone or placebo (110440). The validity of these findings is limited by the lack of blinding.
• Male infertility. It is unclear if oral horse chestnut is beneficial for male infertility. Details: Preliminary clinical research shows that taking horse chestnut seed extract 150 mg (Aescuven Forte), containing aescin 30 mg, twice daily for 2 months increases sperm density, but does not improve sperm motility, in men with varicocele-associated infertility (55493). More evidence is needed to rate horse chestnut for these uses.

• Cognitive function. Oral sage seems to be beneficial for improving cognitive function in healthy adults. The benefits of sage aromatherapy are unclear. Details: Clinical research shows that taking a specific product providing common sage polyphenols and Spanish sage terpenoids (Cognivia), either as a single dose or daily for 29 days, modestly improves working memory and accuracy when compared with placebo. A single dose of this product contains common sage leaf extract 400 mg and Spanish sage essential oil 200 mg (105337). In addition, preliminary clinical research shows that Spanish sage essential oil 25-50 mcL orally as a single dose seems to dose-dependently enhance some measures of cognitive performance in young adults by a small amount (10811,72609,72616,72660). When used as aromatherapy, essential oils of common sage, but not Spanish sage, seem to improve quality of memory and secondary memory. Neither species improves speed of memory or working memory when used as aromatherapy. In this study, five drops of common sage essential oil and 5 mL water were placed on a warmed stone and allowed to diffuse for 5 minutes prior to exposure (72658).
• Hyperlipidemia. Oral sage seems to be beneficial for reducing low-density lipoprotein (LDL) cholesterol and triglyceride levels. Details: Clinical research in adults with mixed hyperlipidemia types shows that taking common sage leaf extract 500 mg, standardized to quercetin 2.16%, three times daily for 2 months reduces LDL cholesterol and triglyceride levels by about 20% and 23%, respectively, and increases high-density lipoprotein (HDL) cholesterol levels by 20%, when compared with placebo (72662). Also, preliminary clinical research in adults with type 2 diabetes and hypercholesterolemia shows that taking common sage leaf extract 500 mg three times daily for 3 months lowers total cholesterol by 17%, LDL cholesterol by 36%, and triglycerides by 56%, and increases HDL cholesterol by 28%, when compared with placebo (91971).
• Menopausal symptoms. Oral sage seems to be beneficial for reducing menopausal symptoms. Details: Clinical research shows that taking a thujone-free common sage extract (Menosan, A.Vogel AG) 280 mg daily for 4 weeks reduces overall symptoms of menopause by 39% when compared with placebo. About 41% of patients taking common sage had at least a 50% reduction in symptoms, compared with 8% of those taking placebo. Hot flushes, sleep problems, joint and muscle discomfort, irritability, and physical and mental exhaustion were improved, whereas urogenital symptoms such as sexual desire and vaginal dryness were not (105338). Other clinical research shows that taking common sage extract 300 mg daily for 3 months moderately reduces overall symptoms of menopause after about 10 weeks when compared with placebo. However, there was no effect on vaginal dryness, physical and mental exhaustion, or urinary incontinence (103379). Another small clinical study shows that taking a specific thujone-free common sage extract (Sage Menopause, Bioforce AG) 280 mg daily for 56 days reduces daily hot flash frequency by 40% and reduces hot flash intensity when compared with baseline (17177). The validity of these findings is limited by the lack of a comparator group.

POSSIBLY INEFFECTIVE

• Postoperative pain. Using an oral rinse containing common sage does not seem to be beneficial for reducing postoperative pain. Details: A large open-label clinical trial in children and adults shows that using a common sage oral rinse 6 times daily in combination with ibuprofen or diclofenac is less effective than benzydamine hydrochloride, a local anesthetic, for reducing pain following tonsillectomy and/or adenoidectomy. Furthermore, treatment with common sage oral rinse is associated with an increased risk of postoperative infection in adults when compared with benzydamine hydrochloride (72700).

• Age-related cognitive decline. It is unclear if a single oral dose of common sage is beneficial for age-related cognitive decline. Details: Clinical research in healthy, older adults shows that taking a single dose of common sage extract 333 mg improves accuracy of attention and some measures of memory when compared with placebo. However, not all doses were effective and some measures of cognitive function were not affected (72642).
• Alzheimer disease. It is unclear if oral sage is beneficial for Alzheimer disease. Details: Preliminary clinical research shows that taking extracts of common sage and Spanish sage orally seems to improve cognitive function in patients with mild to moderate Alzheimer disease when used for up to 4 months (10334,10810). In one study, a fixed dose of common sage hydroalcoholic extract, equivalent to 1 gram of sage per day, was used for 4 months (10810). In the other, an extract of Spanish sage titrated up to 2.5 mg three times daily for 6 weeks was used (10334). These studies are limited by their short duration and small numbers of participants.
• Androgen deprivation therapy (ADT)-associated hot flashes. It is unclear if oral sage is beneficial for ADT-associated hot flashes. Details: Preliminary clinical research in patients with prostate cancer receiving ADT shows that taking common sage extract 150 mg three times daily with meals for 4 weeks reduces hot flash severity by 48% and hot flash frequency by 42% when compared with baseline. These improvements were maintained with an additional 8 weeks of treatment (91970). The validity of these findings is limited by the lack of a comparator group.
• Athletic performance. It is unclear if oral sage is beneficial for improving athletic performance. Details: In young, healthy, physically active adults, taking a specific supplement (Cognivia, Nexira) containing 400 mg common sage leaf extract and 200 mg Spanish sage oil, orally 2 hours prior to a 40-minute stationary cycling session at 80% of maximum aerobic power, lowers perceived exertion scores and improves working memory and reaction times when compared with placebo (108961).
• Chemotherapy-induced nausea and vomiting (CINV). It is unclear if topical sage is beneficial for the treatment or prevention of CINV. Details: A small clinical study in patients undergoing chemotherapy shows that using common sage oil 2 mL topically during 15-minute sessions of Swedish abdominal massage twice daily for 3 days modestly reduces nausea severity scores, but does not affect vomiting frequency, when compared with massage alone (107023).
• Dental plaque. It is unclear if rinsing the mouth with sage is beneficial for reducing plaque. Details: Preliminary clinical research shows that rinsing the mouth with 10-15 mL of a solution containing common sage, twice for 30 seconds four times daily for 4 days, in addition to standard oral care with brushing and use of an oral gel (Biotene), is as effective as normal saline for reducing dental plaque. However, there was no effect on tongue plaque. The rinse was made by steeping 2.5 grams of dried sage leaf in 100 mL boiled water for two minutes (105339).
• Diabetes. It is unclear if oral sage is beneficial for diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking common sage leaf extract 500 mg three times daily for 3 months lowers fasting blood glucose by 32% and glycated hemoglobin (HbA1c) by 23% when compared with placebo (91971). However, another small clinical study in patients with type 2 diabetes shows that taking common sage extract 150 mg three times daily for 3 months does not lower fasting blood glucose or HbA1c when compared with placebo, although there is a modest reduction in 2-hour postprandial blood glucose levels (105340). A meta-analysis of 3 small studies, including the 2 described above, shows that taking common sage, 150-500 mg three times daily for 2-3 months, modestly reduces fasting blood glucose and 2-hour postprandial blood glucose levels, as well as HbA1c, when compared with placebo (108962). These studies were all conducted in Iran; it is unclear if these findings are generalizable to other geographic locations.
• Dry mouth. It is unclear if rinsing the mouth with common sage is beneficial for dry mouth. Details: Preliminary clinical research in patients receiving palliative cancer care shows that rinsing the mouth with 10-15 mL of a solution containing common sage, twice for 30 seconds four times daily for 4 days, in conjunction with standard care involving brushing and an oral gel (Biotene), is as effective as normal saline for improving overall oral health and modestly more effective than normal saline for improving dry mouth. The rinse was made by steeping 2.5 grams dried sage leaf in 100 mL boiled water for two minutes (105339).
• Gingivitis. Sage has only been evaluated as a mouthwash in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in elderly individuals shows that rinsing the mouth with a mouthwash containing sage, marshmallow, calendula, tormentil, horse chestnut, neem, and myrrh, once daily for 30 seconds for 6 weeks, is no more effective than placebo for improving plaque and gingival bleeding (105341).
• Herpes labialis (cold sores). It is unclear if topical sage is beneficial for herpes labialis. Details: Clinical research shows that topical application of a cream containing either sage alone or sage with rhubarb, starting within 1 day of the first symptoms and continuing for 10-14 days, heals herpes labialis legions in 7.6 days or 6.7 days, respectively, compared to a healing time of 6.3 days with acyclovir cream. The combination of sage and rhubarb also improves the time to healing and reduces pain when compared with sage alone. The cream provided 23 mg sage extract, with or without 23 mg rhubarb extract, per gram and was applied every 2-4 hours while awake (10437).
• Lung cancer. It is unclear if dietary sage is beneficial for lung cancer prevention. Details: Epidemiological research has found that regularly consuming sage is associated with a 54% lower risk of developing lung cancer when compared with those who do not use sage as a spice (72593).
• Oral mucositis. It is unclear if rinsing the mouth with sage is beneficial for oral mucositis. Details: Preliminary clinical research in patients receiving palliative cancer care shows that rinsing the mouth with 10-15 mL of a rinse containing common sage, twice for 30 seconds four times daily for 4 days, in addition to standard oral care with brushing and use of an oral gel (Biotene), does not improve oral mucositis when compared with baseline or normal saline rinse. The rinse was made by steeping 2.5 grams of dried sage leaf in 100 mL boiled water for two minutes (105339).
• Pharyngitis. It is unclear if inhaling a spray containing sage, with or without other ingredients, is beneficial for pharyngitis. Details: Clinical research in patients with acute viral pharyngitis shows that inhaling three puffs (140 mcL) of a specific spray (Valverde Salvia Rachenspray) containing common sage extract 15%, six to nine times daily for 3 days, reduces throat pain intensity over 2 hours when compared with placebo. However, sprays containing common sage extract 5% or 30% do not seem to be more effective than placebo for reducing throat pain (72619). Other preliminary clinical research in patients with sore throat due to acute pharyngitis or tonsillitis shows that applying a combination spray product containing common sage leaf tincture 430 mg/mL, Echinacea flowering aerial parts tincture 863.3 mg/mL, and Echinacea root tincture 45.5 mg/mL, every 2 hours up to 10 times daily for up to 5 consecutive days improves symptoms as effectively as a chlorhexidine-lidocaine spray (20077).
• Polycystic ovary syndrome (PCOS). It is unclear if oral sage is beneficial for PCOS. Details: Clinical research shows that taking common sage extract 330 mg daily for 8 weeks modestly reduces body mass index (BMI), diastolic blood pressure, and fasting blood glucose, and modestly improves measures of insulin resistance, when compared with placebo in individuals with PCOS. However, there was no effect on waist to hip ratio or systolic blood pressure (103380).
• Sunburn. It is unclear if topical sage is beneficial for sunburn prevention. Details: Clinical research shows that a single application of a hydrophilic ointment containing common sage extract 2% to the skin immediately after exposure to ultraviolet light reduces the development of skin redness when compared with placebo (72638).
• Swallowing dysfunction. It is unclear if rinsing the mouth with sage is beneficial for swallowing dysfunction. Details: Preliminary clinical research in patients receiving palliative cancer care shows that rinsing the mouth with 10-15 mL of a solution containing common sage, twice for 30 seconds four times daily for 4 days, in addition to standard oral care with brushing and use of an oral gel (Biotene), does not improve swallowing when compared with baseline or normal saline rinse. The rinse was made by steeping 2.5 grams of dried sage leaf in 100 mL boiled water for two minutes (105339).
• Tonsillitis. Sage has only been evaluated in a spray in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with sore throat due to acute pharyngitis or tonsillitis shows that applying a combination spray product containing common sage leaf tincture 430 mg/mL, Echinacea flowering aerial parts tincture 863.3 mg/mL, and Echinacea root tincture 45.5 mg/mL, every 2 hours up to 10 times daily for up to 5 consecutive days improves symptoms as effectively as a chlorhexidine-lidocaine spray (20077).
• Tonsillopharyngitis. It is unclear if oral sage is beneficial for treating tonsillopharyngitis. Details: A moderate-sized observational study in patients aged 12-75 years old with acute tonsillopharyngitis suggests that taking lozenges containing sage extract 378.5 mg and echinacea extract 5 times daily for 4 days reduces throat pain and tonsillopharyngitis symptoms when compared to baseline, both acutely within 90 minutes and after 4 days of treatment (111530). The validity of these findings is limited by the lack of a comparator group. Also, it is unclear if these effects are due to sage, echinacea, the combination, or natural resolution of the condition. More evidence is needed to rate sage for these uses.

POSSIBLY INEFFECTIVE

• Urinary tract infections (UTIs). Clinical research does not support the use of oral uva ursi for treatment of UTIs. For prevention of UTIs, oral uva ursi has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical study in females with uncomplicated UTI shows that taking uva ursi tablets providing 210 mg arbutin orally three times daily for 5 days is less effective than a single dose of fosfomycin 3 grams for reducing UTI symptom burden and the number of rescue antibiotic courses. Rescue antibiotics were needed in 44% of patients receiving uva ursi, compared with 23% of those receiving fosfomycin. On day 4, the percentage of patients with symptom resolution was 49% with uva ursi, compared to 65% with fosfomycin. Pyelonephritis occurred in 8 patients on uva ursi and 2 patients on fosfomycin (109535). Also, a large clinical study in females experiencing symptoms of a UTI shows that taking uva ursi extract 1200 mg three times daily for 3-5 days does not improve symptoms or reduce the need for antibiotics when compared with placebo (101815). Uva ursi has also been evaluated for the prevention of UTIs. One small clinical study in females with recurrent UTI shows that taking a specific combination product containing uva ursi and dandelion (UVA-E, Medic Herb AB) 3 tablets three times daily for one month reduces the recurrence rate of UTIs when compared with placebo (1932). It is not clear if this effect is due to uva ursi, dandelion, or the combination.

Cardiovascular ...Orally, there is one case report of pericardial tamponade following exudative pericardial effusion in a previously healthy 32-year-old male who consumed three boxes of horse chestnut paste over 6 weeks. The patient was treated with steroid therapy for 2 months, as well as colchicine 0.5 mg twice daily and ibuprofen 600 mg twice daily for 3 months. These cardiovascular events were considered to be possibly related to the antiplatelet activity of horse chestnut or to an immunologic response to antigens present in horse chestnut paste (91972). A case of atrial fibrillation is also reported in a previously healthy 46-year-old male after accidental ingestion of a horse chestnut seed. The patient also presented with abdominal pain, nausea, sweating, and palpitations. The arrhythmia resolved within a few hours without medical intervention (110439).

Dermatologic ...Orally, horse chestnut seed extract has been reported to cause pruritus (282,12113,55486).

Gastrointestinal ...Orally, horse chestnut seed extract has been reported to cause nausea, vomiting, diarrhea, abdominal pain, constipation, dry mouth, gastrointestinal upset, and dyspepsia (282,12113,55477,55486,55493,55520,110439).

Hepatic ...Orally, there is one case report of hepatotoxicity in a 69-year-old female who took 6-15 tablets of a specific product (Venencapsan) containing horse chestnut leaf, milfoil, celandine, sweet clover, milk thistle, and dandelion root daily for 6 weeks. The patient's symptoms disappeared 6 weeks after discontinuing the product and reappeared following re-initiation (55518). Another case report describes a 70-year-old male presenting with acholia, choluria, and jaundice after 3 weeks of self-treatment with an unspecified dose of a specific combination product (Venenkraft) containing horse chestnut. The patient presented with elevated liver transaminase and bilirubin levels, and was diagnosed with drug-induced liver injury. Following discontinuation, laboratory values and symptoms progressively resolved (107702). In both of these case reports, it is unclear if hepatotoxicity was due to horse chestnut, another ingredient, or the combination.
