Thuja occidentalis

Prepared from the fresh green twigs and leaves of the Thuja occidentalis tree, a member of the Cupressaceae family, native to North America. The essential oil contains thujone, a neurotoxin in large doses.

Proved by Samuel Hahnemann; published in Materia Medica Pura and Chronic Diseases

Thuja reflects the shadow of suppressed self-expression. Its core is the split between outer composure and inner corrosion. The sycotic miasm brings overgrowth, secrecy, shame, and dissimulation. The patient may appear polished or reserved but wrestles internally with feelings of uncleanliness, fragmentation, and invasion—whether through vaccination, infection, or moral guilt. It is a remedy of duality: the seen vs. the hidden, the body vs. the perceived foreign presence. Ideal for aftereffects of vaccination, gonorrhoea, or suppressed skin ailments.
