Study of immune responses in mice to oral administration of Flor·Essence.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Flor·Essence (FE), a natural food grade herbal formula product manufactured by Flora Manufacturing & Distributing Ltd., has been used by patients with cancer in North America to stimulate immune cells in order to attenuate or reverse immune damage. To elucidate the mechanisms underlying the effects of FE on the immune system, spleen lymphocyte proliferation was analyzed by an MTT assay, and the phagocytic capacity of macrophages was measured via the neutral red phagocytosis method. The cytotoxicity of natural killer (NK) cells towards K562 cells was assessed via a CytoTox 96 assay. The production of the cytokines interleukin (IL)-12 and interferon (IFN)-γ in the peripheral blood was determined via ELISA and PCR analysis. The expression levels of caveolin-1 and NF-κB were measured via western blotting. In addition, cyclophosphamide was used to establish a mouse model of immunosuppression. It was found that the proliferation of splenocytes, the phagocytic capacity of macrophages and the cytotoxicity of NK cells against K562 cells were increased after oral administration of FE to mice. FE augmented the production of IL-12 and IFN-γ in the peripheral blood of mice. FE significantly increased the expression of proliferating cell nuclear antigen and caveolin-1, and decreased NF-κB expression. Finally, FE enhanced the viability of immune cells from cyclophosphamide-treated immunosuppressed mice. The results indicated that FE could activate immune responses and enhance natural immunity, suggesting that oral administration of FE can activate the body's immune response and resist damage caused by cyclophosphamide chemotherapy.
