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.

Traditionally used in herbal medicine for warts, respiratory ailments, and as an astringent. Also utilised ornamentally and as an antiseptic.

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.

• Classic remedy for warts, condylomata, and sycotic miasm
• Indicated for post-vaccination effects, including behavioural change
• Useful in chronic urinary or genital tract conditions
• Consider for chronic fatigue, neuralgia, or mental disturbances after suppression
