Pregnancy, Breastfeeding & Children

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

Pregnancy

Use Caution

This herb may affect blood pressure. Since blood pressure changes are a significant pregnancy risk factor (e.g. preeclampsia), herbs in this category are generally used only under medical supervision rather than self-directed — this is a general, mechanism-based caution, not herb-specific research.

Breastfeeding

Use Caution

Generally used cautiously during breastfeeding, particularly if the nursing parent is also on blood pressure medication.

Children

Use Caution

Blood-pressure-active herbs are generally used cautiously in children and typically only under pediatric guidance.

Interactions & contraindications

May affect blood pressure

Watch for: Antihypertensive medications (ACE inhibitors, beta-blockers, calcium channel blockers, diuretics)

Combined use can push blood pressure too high or too low — monitor readings if you take blood pressure medication.

May thin the blood

Watch for: Anticoagulants (warfarin), antiplatelets (aspirin, clopidogrel), and other blood-thinning herbs or supplements (ginkgo, garlic, fish oil, vitamin E)

Combining blood-thinning substances can increase bleeding risk, including before surgery or dental work.

May affect immune activity

Watch for: Immunosuppressants (for transplant or autoimmune conditions)

Immune-stimulating herbs can work against immunosuppressive therapy.
