23 peer-reviewed studies
What the evidence says
Mostly mechanism / observational
Most Wormwood studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 2004–2026 with a typical study size of 50 participants.
Based on 21 studies · 1 meta-analysis · 14 RCTs · 50 total participants

Furthermore, Artemisia 's contributions to sustainable agriculture, functional foods, and cosmeceuticals underline its adaptability and economic significance.
However, gaps in clinical validation, sustainable cultivation, and regulatory frameworks remain barriers to fully harnessing its potential.
Future multidisciplinary research and ethical policies are essential to integrate Artemisia more effectively into global health and industry.
In plain English: This underscores the need for further exploration of its therapeutic potential.

These compounds inhibit cancer cell proliferation, invasion, and metastasis, and induce apoptosis by regulating pathways like PI3K/AKT, JAK-STAT, p53, and GPX4.
They also modulate the immune and tumor microenvironment, enhancing chemotherapeutic drug efficacy.
Conclusion The active ingredients of Artemisia annua L. show great potential for cancer treatment, highlighting its broad applications and clinical value.
In plain English: These results demonstrate that AA compounds have significant potential as adjuncts or alternatives in cancer management and warrant rigorous evaluation in standardized clinical trials.

Among the included studies, six of seven eligible studies (86%) reported measurable reductions in tumor size or volume, and four documented apoptosis induction.
So far, the possibility of dose- or regimen-dependent toxicities reported elsewhere in the literature is not excluded; however, further comprehensive studies are needed to confirm this.
This review is the first to consolidate recent preclinical evidence highlighting ferroptosis as one of the key mechanisms of AA derivatives, thereby expanding the understanding of their multifaceted anticancer activity.
In plain English: Conclusions Coseasonal initiating Artemisia annua SLIT demonstrated clinical efficacy and safety for children and adult patients with ARC.

Compared with the baseline, the levels of total rhinoconjunctivitis symptom score (TRSS), total medication score (TMS), and combined symptom and medication score for rhinoconjunctivitis (CSMS-RC) experienced significant reductions after 1 year SLIT.
Additionally, these outcomes also decreased significantly in SLIT group when compared with the control group during 2023 pollen season.
Especially, there were more patients showed symptoms reduction, medication use decrease, and efficacy improvement in the SLIT group.
