Rehmannia 1000 mg by Remedys Nutrition

POSSIBLY EFFECTIVE

• Chronic kidney disease (CKD). Oral rehmannia acteosides might reduce proteinuria when used in conjunction with angiotensin II receptor blockers in patients with CKD. Details: A large clinical trial in adults with chronic glomerulonephritis shows that taking rehmannia acteosides extract 400 mg twice daily, in conjunction with irbesartan 150 mg daily, for 8 weeks decreases proteinuria by 36%, compared with a reduction of 28% with irbesartan alone (93662).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aplastic anemia. It is unclear if oral rehmannia is beneficial in patients with aplastic anemia. Details: A small clinical study in adults with aplastic anemia shows that taking rehmannia polysaccharide (dose unknown), in conjunction with stanozolol, increases the incidence of symptom remission by 45% when compared with stanozolol alone (70704).
• Atopic disease. Although there has been interest in using oral rehmannia for atopic disease, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Diabetes. Although there has been interest in using oral rehmannia for diabetes, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Diabetic nephropathy. Oral rehmannia has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical study in adults with chronic kidney disease due to type 2 diabetes receiving standard care with an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker shows that taking a specific combination product (Rehmannia-6, PuraPharm) containing rehmannia, Japanese cornel dogwood, wild yam, poria mushroom, Asian water plantain, and peony root bark twice daily for 48 weeks modestly slows the decline in kidney function when compared with standard care alone (112821). It is unclear if this effect is due to rehmannia, other ingredients, or the combination.
• Metabolic syndrome. Although there has been interest in using oral rehmannia for metabolic syndrome, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Obesity. It is unclear if oral rehmannia root extract is beneficial in patients with obesity. Details: A very small clinical study in females with obesity shows that taking steamed rehmannia root extract 4 grams twice daily for 8 weeks decreases waist circumference by 2.6%, but does not affect body weight or body fat percentage, when compared to baseline (93660). The validity of these findings is limited by the lack of a control group.
• Osteoporosis. Although there has been interest in using oral rehmannia for osteoporosis, there is insufficient reliable information about the clinical effects of rehmannia for this purpose.
• Rheumatoid arthritis (RA). Although there has been interest in using oral rehmannia for RA, there is insufficient reliable information about the clinical effects of rehmannia for this purpose. More evidence is needed to rate rehmannia for these uses.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, rehmannia might increase the risk of hypoglycemia when taken with antidiabetes drugs.  Details Animal research shows that rehmannia may have hypoglycemic effects (15061,93668).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, rehmannia might increase the risk of hypotension when taken with antihypertensive drugs.  Details Animal research shows that rehmannia may have hypotensive effects. Laboratory research shows that formulations of dried and processed rehmannia root inhibit angiotensin-converting enzyme (ACE) (104272).
