No information on the safety of yin-chen wormwood herb or above-ground parts in pregnancy or lactation was identified in the scientific or traditional literature. Although this review did not identify any concerns for use while pregnant or nursing, safety has not been conclusively established. 

Rare cases of adverse events have been reported in persons taking relatively high (15 to 30 g) doses of yin-chen wormwood. Symptoms included headache, dizziness, numbness and tremor of the upper extremities, heart palpitations, fainting, and an oppressive feeling in the chest. Details on the exact doses, preparation, and relevant medical history were not reported (Bensky et al. 2004). 

Of 75 compounds isolated from yin-chen wormwood, 15 showed antiplatelet aggregation activity (Wu et al. 2001). 

No information on the safety of yin-chen wormwood during pregnancy or lactation was identified. 

No mutagenic activity of an aqueous extract of yin-chen wormwood was observed in the Ames mutagenicity assay with Salmonella typhimurium strains TA98 or TAIOO with or without metabolic activation by S9 (Yin et al. 1991). 

In the mouse micronucleus and chromosomal aberration assays, some mutagenic activity was observed in mice intraperitoneally administered an aqueous extract of yin-chen wormwood at doses of 4.5, 9, or 18 g/kg. In the micronucleus assay, an increase of polychromatic erythrocytes was observed at the 4.5,9, and 18 g/kg dose levels. An increase in the incidence of chromosomal aberrations was observed at the 4.5,9, and 18 g/kg dose levels, but not at the 0.9 g/kg dose level (Yin et al. 1991).
