Medicinal preparations:


Dried herb can be used in tea, capsules, steam inhalations and syrups.


This plant is primarily used internally (from what I have read so far).


Do not use if pregnant or nursing, or in children without the advice of a qualified healthcare practitioner. May interact with anti-inflammatory medications, or those prescribed for asthma, spasms, bronchitis or other respiratory illnesses. This herb has not been extensively researched in modern medicine.

I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns.

Energetic/traditional use:

This carnivorous plant was once reputed to cure warts and cause milk to spoil – but more commonly it was revered as an aphrodisiac and a potent pulmonary remedy even centuries ago.
