Solicitor Tertius van Eeden asked the court to release her on bail.
Judge Dempsey noted there was no garda objection but said the woman could not be found for three years.
Denying bail, he remanded her in custody to appear again on Friday.
Legal aid was granted as well as an order for disclosure of evidence.
The charge is under section 15 of the Non- Fatal Offences Against the Person Act for using or threatening to use violence in public, with several others, causing a person to fear for their own or another person's safety.
