INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. Although there is interest in using oral and topical asparagus for acne, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Cancer. Although there is interest in using oral asparagus for cancer, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Constipation. Although there is interest in using oral asparagus for constipation, there is insufficient reliable information about the clinical effects of asparagus for this purpose.
• Intestinal parasite infection. Although there is interest in using oral asparagus for intestinal parasite infection, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Hypertension. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with hypertension shows that taking a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams daily for 6 weeks does not affect ambulatory blood pressure when compared with baseline (94940).
• Kidney stones (nephrolithiasis). Although there is interest in using oral asparagus for kidney stones, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Obesity. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in overweight adults shows that taking psyllium 2-3 tablespoons each morning with 1.5 liters of elderflower juice, plus tablets providing asparagus powder 2.7 grams, elderberry powder 225 mg, and elderflower extract 600 mg daily for 2 weeks, and replacing each meal on days 5-12 with 200 mL of elderberry and elderflower juice, is associated with an average 3.2 kg weight loss and a modest reduction in blood pressure when compared with baseline (94939). It is not known if these effects are due to asparagus, other ingredients, the combination, or fasting from regular food for 8 days. Furthermore, the validity of these findings is limited by the lack of a comparator group.
• Rheumatoid arthritis (RA). Although there is interest in using oral asparagus for RA, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Urinary tract infections (UTIs). Although there is interest in using oral asparagus for UTIs, there is insufficient reliable information about the clinical effects of asparagus for this condition. More evidence is needed to rate asparagus for these uses.
