The participants (average age of 40; 84 women, 44 men) were assigned to 1 of 3 interventions:

Low dose of Heptex (1 capsule daily)
High dose of Heptex (2 capsules daily)
Placebo

Each Heptex capsule contained 200 milligrams of dukung anak (also called gale of the wind; extract from aerial parts of Phyllanthus niruri) and 100 milligrams of milk thistle (an extract of Silybum marianum fruits).

Although the abstract reported improved liver enzymes in the Heptex groups, there were similar improvements in the placebo group, with no statistically significant differences between the groups.

In addition, one of the researchers was employed by Natural Wellness Industries, the manufacturer of Heptex, at the time the trial was conducted.
