Twenty-four-week oral dosing toxicities of Herba Siegesbeckiae in rats.
Article in BMC complementary medicine and therapies, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundHerba Siegesbeckiae (HS), the dried aerial parts of Siegesbeckia orientalis L., S. pubescens Makino, or S. glabrescens Makino, is traditionally used for treating chronic diseases in China. However, there is no information about the chronic toxicity of HS. The objective of this study is to evaluate the 24-week oral dosing toxicities of HS aqueous extract (HSE) in rats.
methodsS. orientalis-originated HS was reflux-extracted with distilled water. Sprague-Dawley rats were randomly divided into four groups, with 10 males and 10 females in each group. The rats were intragastrically administered with HSE at 5, 1.67 and 0.56 g/kg (experimental groups) or an equal volume of distilled water (control group), 6 days a week, for 24 weeks. The high dose of HSE (5 g/kg) was its maximum tolerated dose. Body weight was recorded every 2 days during the experimental period. Chemical, hematological and histopathological parameters, as well as organ weights, were measured at the end of the experiment.
resultsDecreased body weight gain; increased liver and lung relative weights; histopathological alterations in liver and lung tissues; elevated serum levels of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase were found after HSE treatments. In liver tissues, HSE treatment upregulated levels of three pro-inflammatory cytokines: IL-6, IL-1β and TNF-α. In lung tissues, HSE treatment caused oxidative stress and activated mitogen-activated protein kinases (MAPKs).
conclusionLong-term oral administration of HSE caused toxicities in rats evidenced by decreased body weight gain, as well as liver and lung damage. Treatment-induced oxidative stress, inflammation and MAPK activation are involved in HSE's toxicities. Caution should be taken when using HS to treat chronic diseases.
