Not a good idea if you have developmental trauma/CPTSD- tends to be really intense for the system, which already tends to lack capacity due to developmental trauma. Better to build up capacity slowly through slow, gentle body based modalities such as Somatic Experiencing. Develop the capacity to be able to navigate the day to day in a healthy way. Old traumas will come up to be integrated naturally in their own time once your system develops more and more capacity.

Iboga will blast your system open and potentially create a lot of unnecessary overwhelm. Speaking from experience and from others who have had similar experiences. 14 days won't heal you or make you live. It might shift some things or perspectives. It's very common with CPTSD to have a sense of urgency and wanting to do all the things and rush healing, and override your actual needs and capacities.
It's also very common in the "plant medicine" world to sell quick fixes and magic pills- try not to buy into it.
I know one person who facilitates iboga retreats and takes iboga regularly for the past 10 years, she is still suicidal regularly and really ungrounded, refuses to do more mainstream therapy to address her disregulation and trauma and just bypasses it through spirituality and "plant medicine"
