arrow  Back to Research

Aller-7® is a patented blend of seven standardized herbal extracts. Its safety and tolerability profile has also been determined in previous studies. The current 12-week investigation evaluated the effects of Aller-7® in 545 subjects at 14 research centers. A double-blind, placebo-controlled trial with 171 subjects was conducted at 3 clinical centers, while 374 subjects were enrolled in an open-label trial at 11 sites. Subjects in the placebo-controlled trial were randomly assigned to receive 4 capsules of Aller-7® daily (1,320 mg of Aller-7®), or placebo capsules identical in appearance. Over the 12-week period, 94% of subjects in the open-label trials and 92% of subjects in the placebo-controlled trials taking Aller-7® reported a benefit in maintaining their respiratory health. No serious side-effects were observed, thus demonstrating that Aller-7® is both well-tolerated and efficacious in supporting respiratory health. These results are consistent with those of previous clinical studies.
