Pregnancy, Breastfeeding & Children
No herb-specific pregnancy/child safety research is documented for Rau Sam (Purslane) in our references — the guidance below is based on its general effect category, not research on Rau Sam (Purslane) itself. Always confirm with a midwife, doctor, or pediatrician.
Pregnancy
Use CautionThis 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 CautionGenerally used cautiously during breastfeeding, particularly if the nursing parent is also on blood pressure medication.
Children
Use CautionBlood-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 blood sugar
Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)
Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.
