Abstract

Artemisia sp., especially A. annua and A. afra, have been used for centuries to treat many ailments. While artemisinin is the main therapeutically active component, emerging evidence demonstrates that the other phytochemicals in this genus are also therapeutically active. Those compounds include flavonoids, other terpenes, coumarins, and phenolic acids. Artemisia sp. phytochemicals also improve bioavailability of artemisinin and synergistically improve artemisinin therapeutic efficacy, especially when delivered as dried leaf Artemisia as a tea infusion or as powdered dry leaves in a capsule or compressed into a tablet. Here results from in vitro, and in vivo animal and human studies are summarized and critically discussed for mainly malaria, but also other diseases susceptible to artemisinin and Artemisia sp. including schistosomiasis, leishmaniasis, and trypanosomiasis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Analysis of dried leaf samples harvested pre-anthesis over that time had artemisinin and total flavonoid contents of 1.3 ± 0.2% and 0.5 ± 0.09% (w/w), respectively.

    “Analysis of dried leaf samples harvested pre-anthesis over that time had artemisinin and total flavonoid contents of 1.3 ± 0.2% and 0.5 ± 0.09% (w/w), respectively.”

    In “What in these Artemisia sp. is therapeutically effective?” (page unavailable), the paper reports seven-year averages of 1.28 ± 0.23% artemisinin and 4.63 ± 0.90 mg/g dry-weight flavonoids. These round or convert to the claimed values, but the passage does not establish that the samples were harvested pre-anthesis. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The Weathers lab reported artemisinin levels and total flavonoid content of the SAM cultivar of A. annua propagated at least annually over 7 yrs only by rooted cuttings and grown in different soil locations, in pots in growth chambers and on lighted windowsills.

    “The Weathers lab recently reported artemisinin levels and total flavonoid content of the SAM cultivar of A. annua that was propagated at least annually over 7 yrs only by rooted cuttings and grown in different soil locations, in pots in growth chambers and on lighted windowsills (Gruessner et al. 2019).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
