Baccharis halimifolia

Please read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: This species is poorly documented in traditional herbalism and certain parts of the plant are considered toxic to livestock, which calls for great caution. Do not consume without advice from a qualified professional, as internal use is not sufficiently established or safe. Avoid all use during pregnancy or breastfeeding, as well as in children, due to lack of data. Baccharis halimifolia is classified as an invasive species in several regions, particularly in Europe; its harvesting and cultivation may be regulated.

Decoction — Seeds / fruits

Traditional decoction (reported historical use)

Some historical sources mention a light decoction of the seeds, without the exact process or proportions being clearly established. A healthcare professional or experienced herbalist must be consulted before any use. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant

Baccharis halimifolia is found growing wild on the North American Atlantic coast, in salt marshes and dunes; it is seldom offered in traditional French herbalism due to its status as an invasive species and limited documentation on its uses.

Harvest season

When to harvest

Fruits and seeds are traditionally harvested in autumn, when the downy seed heads appear on female branches.
