POSSIBLY SAFE ...when the leaf extract is used orally and appropriately. There is some evidence that boxwood leaf extract can be used safely for up to 16 months (5643).
LIKELY UNSAFE ...when the whole leaf is used orally (12,18). The whole boxwood leaf can cause life threatening side effects including seizures, paralysis, and death by asphyxiation (18).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when the whole leaf is used orally (12,18); avoid using.
There is insufficient reliable information available about the safety of boxwood leaf extract when used during pregnancy and lactation; avoid using.

Evidence from in vitro research suggests that boxwood extract can inhibit acetylcholinesterase activity (37067). Theoretically, concurrent use of anticholinergic drugs and boxwood might decrease the effectiveness of boxwood or the anticholinergic agent.

General
...Orally, boxwood leaf extract seems to be well tolerated (5643).
However, ingestion of whole boxwood leaf can cause serious side effects including vomiting, diarrhea, severe colonic spasms, paralysis, and death secondary to asphyxiation (18).
Topically, the fresh plant and wood can cause allergic contact dermatitis (18,37073).
When inhaled, the wood dust can cause rhinoconjunctivitis and bronchitis (99904).
Gastrointestinal ...Orally, ingestion of whole boxwood leaf can cause serious side effects including vomiting, diarrhea, and severe colonic spasms (18). The extract, however, does not seem to have these effects (5643).
Immunologic ...Occupational exposure to boxwood dust might cause allergic symptoms. In a case report, a 52-year-old male experienced symptoms such as rhinoconjunctivitis and bronchitis following occupational exposure to boxwood wood dust (99904). Cases of allergic contact dermatitis to fresh boxwood leaves and a boxwood recorder have also been reported (18,37073).
Neurologic/CNS ...Orally, ingestion of whole boxwood leaf can cause serious side effects including paralysis and death secondary to asphyxiation (18). The extract, however, does not seem to have these effects (5643).
