Chaparral

Larrea tridentata
leafhigh-riskavoid-internalliver-risktraditionaltopical-only

Chaparral is a desert shrub with a long history of traditional use, but internal use is associated with serious safety concerns—especially liver toxicity. Because the risk is significant and the benefit claims are often exaggerated, chaparral should be treated as a high-risk herb. If used at all, it should be framed as avoid-internal, with a strong safety warning.

Key Benefits

Common Issues It May Help With

How To Use (Simple)

Taste / Notes

Resinous and bitter (not recommended internally).

Evidence Level

Safety concerns outweigh evidence for internal benefits in self-care use. Reports of liver injury exist with internal chaparral products.

Cautions

HIGH RISK: Do not use internally. Avoid during pregnancy/breastfeeding. Avoid if you have liver disease or take liver-impacting medications. Stop and seek medical care immediately if signs of liver trouble occur (yellowing skin/eyes, dark urine, severe fatigue, abdominal pain).

Interactions

Potential additive liver stress with hepatotoxic medications/supplements Avoid with alcohol due to liver burden If on any chronic medications, do not use internally
