Brazil Nut
fat
Brazil nut refers to a South American tree of the monotypic genus Bertholletia in the family Lecythidaceae as well as the tree's commercially-harvested edible seeds. It is one of the largest and longest-lived trees in the Amazon rainforest. The fruit and its nutshell – containing the edible nut – are relatively large and weigh as much as 2 kg (4.4 lb) in total. As food, Brazil nuts are notable for diverse content of micronutrients, especially a high amount of selenium. The wood of the Brazil nut tree is prized for its quality in carpentry, flooring, and heavy construction.
Conditions addressed
How to use
- Use as a cooking medium on low heat, or drizzle raw over finished dishes to preserve beneficial fatty acids.
Pregnancy, Breastfeeding & Children
No herb-specific pregnancy/child safety research is documented for Brazil Nut in our references — the guidance below is based on its general effect category, not research on Brazil Nut 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.
