Randomized, Double-Blind Clinical Trial to Assess the Acute Diuretic Effect of Equisetum arvense (Field Horsetail) in Healthy Volunteers

Table 2

Intragroup comparisons of fluid balance (𝑛=36/group). The values represent the means ± SD, and the significance was set at 𝑃<0.05.

Group	Fluid Balance
	FB0 (mL)	FB (mL)	FFB (mL)	P
A	844.43±632.72	522.62±463.03	−321.81±481.02	<0.001*
B	773.86±955.37	542.01±935.37	−231.84±726.60	0.067
C	634.69±511.46	763.21±482.45	130.27±534.30	0.164

Groups: A: Equisetum arvense; B: hydrochlorothiazide; C: placebo. FB0: initial fluid balance without treatment; FB: FB after treatment; FFB: final fluid balance (FB − FB0).
*P < 0.05.
