Pregnancy, Breastfeeding & Children

No herb-specific pregnancy/child safety research is documented for Mastic Gum in our references — the guidance below is based on its general effect category, not research on Mastic Gum itself. Always confirm with a midwife, doctor, or pediatrician.

Pregnancy

Use Caution

This herb is processed through the liver, which is already working harder during pregnancy — generally used cautiously and not at high/concentrated doses without guidance. This is a general, mechanism-based caution, not herb-specific research.

Breastfeeding

Use Caution

Liver-processed compounds can appear in breast milk — generally used cautiously and in moderation.

Children

Use Caution

A child's liver is still developing its full drug/herb-processing capacity — these herbs are generally used cautiously and at reduced, age-appropriate doses.

Contraindications

  • Active liver disease — monitor liver enzymes with long-term use

Warnings

⚠️ Liver Health

Some herbs used for liver conditions can be hepatotoxic at high doses. Have liver function monitored if using long-term.

Discontinue immediately if you experience rash, itching, swelling, or difficulty breathing.

Quality tips

When buying Mastic Gum, look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
