POSSIBLY INEFFECTIVE

• Bowel preparation. Taking cascara sagrada orally with magnesium sulfate or magnesium hydroxide prior to colonoscopy does not appear to improve bowel cleansing when used alone or as an adjunct to polyethylene glycol. Details: Some clinical research shows that taking a specific combination of cascara sagrada plus magnesium sulfate (Pico-Salax) orally along with polyethylene glycol (GoLYTELY) is not more effective than polyethylene glycol alone for bowel preparation prior to colonoscopy (40086). Other clinical research shows that taking cascara sagrada plus magnesium sulfate orally, alone or in combination with polyethylene glycol (GoLYTELY), is actually less effective than polyethylene glycol alone (40087,40088). Additionally, some clinical research shows that taking a combination of cascara sagrada 5 mL plus milk of magnesia 30 mL orally does not improve bowel cleansing or examination quality when compared with no bowel preparation (40090,40093).

• Constipation. It is unclear if oral cascara sagrada is beneficial in patients with constipation. Details: Cascara sagrada has a history of use for its laxative effects in patients with constipation (272). In fact, cascara sagrada was formerly approved by the US Food and Drug Administration (FDA) as a safe and effective over-the-counter (OTC) laxative; however, this designation was removed in 2002 due to a lack of supporting evidence (8229). More evidence is needed to rate cascara sagrada for this use.

• ACE inhibitor-induced cough. It is unclear if oral marshmallow root is beneficial in patients with cough due to ACE inhibitors. Details: A small clinical study in patients with ACE inhibitor-induced cough shows that taking marshmallow root 40 mg (20 drops) three times daily for 4 weeks improves cough when compared to baseline (62027). The validity of this finding is limited by the lack of a control group.
• Atopic dermatitis (eczema). It is unclear if topical marshmallow is beneficial in children with eczema. Details: A very small clinical study in children ages 3 months to 12 years with a recent diagnosis of mild to moderate eczema shows that applying a marshmallow 1% ointment twice daily for 1 week and then three times weekly for 3 weeks seems to reduce symptoms, as measured on the SCORing Atopic Dermatitis (SCORAD) scale, when compared with applying hydrocortisone 1% ointment (105437). This finding is limited by the large number of drop-outs due to non-compliance, most of which were in the marshmallow group.
• Breast engorgement. It is unclear if topical marshmallow is beneficial in women with this condition. Details: A small clinical study in breastfeeding women with breast engorgement shows that applying a compress containing 40-50 mL of a solution made from marshmallow leaves and stems 3 times daily for 2 days in conjunction with standard treatment improves patient-reported breast engorgement scores when compared with standard treatment alone. Standard treatment consisted of massage and alternating warm and cold compresses before and after breastfeeding (92845).
• Constipation. Although there is interest in using oral marshmallow for constipation, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Cough. Although there is interest in using oral marshmallow for cough, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Diarrhea. Although there is interest in using oral marshmallow for diarrhea, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Fever. It is unclear if topical marshmallow is beneficial for pediatric fever. Details: A moderate-sized clinical study in children aged 6 months-10 years with fever receiving rectal acetaminophen shows that applying marshmallow extract body wash and lukewarm water reduces the time to defervescence by 8 minutes when compared with lukewarm water alone, but does not improve the change in body temperature, number of acetaminophen doses given, or incidence of fever recurrence (112375). However, the interpretation of these findings is limited to patients without fevers greater than 40 degrees Celsius or history of febrile seizures since these patients were not studied.
• Leishmania lesions. Topical marshmallow has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research suggests that the topical application of an herbal extract containing a combination of marshmallow and Althaea rosa to affected areas for 5 days can help promote curing of Leishmania lesions (62020).
• Respiratory tract infections. Although there is interest in using oral marshmallow for respiratory tract infections, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Vaginal candidiasis. It is unclear if vaginal marshmallow is beneficial for vulvovaginal candidiasis. Details: A small clinical study in adults with vulvovaginal candidiasis shows that applying a vaginal cream comprised of marshmallow extract 4% and clotrimazole 1% daily for 7 days improves itching, dyspareunia, and dysuria at 7 days when compared with clotrimazole 1% alone. At 30 days, the marshmallow intervention also results in fewer positive yeast cultures and sustained reduction in itching (112371). However, the validity of these results is limited by significant differences between groups at baseline for dyspareunia and dysuria, and lack of adjustment for multiple comparisons which can increase false positive findings. Additionally, all primary outcomes were patient-reported.
• Venous leg ulcers. Although there is interest in using topical marshmallow for venous leg ulcers, there is insufficient reliable information about the clinical effects of marshmallow for this condition.
• Wounds. Although there is interest in using topical marshmallow for wounds, there is insufficient reliable information about the clinical effects of marshmallow for this condition. More evidence is needed to rate marshmallow for these uses.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, marshmallow flower might have antiplatelet effects.  Details Animal research suggests that marshmallow flower extract has antiplatelet effects (92846).
