PLANT MEDICINE, PLAINLY
Plant Medicine: What It Means, What's Legal in Indiana, and What's Coming
Short version: "Plant medicine" is a loose, everyday phrase, not a medical category. It gets used for everything from a nightly ashwagandha capsule to an ayahuasca ceremony in another country. Those are not the same kind of thing, and lumping them together is how people end up confused about what is legal, what is studied, and what is actually available to them right now in Indiana.
This page sorts it out. We are a physician-led ketamine therapy practice in Greenwood, Indiana, so we have an obvious stake in one corner of this. We are going to be straight with you about where that corner ends.
THE QUESTION WE GET MOST
Is ashwagandha a psychedelic?
No. Ashwagandha is not a psychedelic and it is not a hallucinogen.
Ashwagandha is Withania somnifera, an evergreen shrub used in Ayurvedic medicine for a very long time. It is usually grouped with the adaptogens, an informal category of herbs marketed for stress and sleep. The National Center for Complementary and Integrative Health fact sheet on ashwagandha describes the plant and its compounds and says nothing about hallucinogenic effects, because there are none to describe.
The confusion is understandable. Ashwagandha shows up in the same online spaces as psychedelics, in the same wellness aisles, sold by some of the same brands, wrapped in the same "ancient plant wisdom" language. But the mechanisms are not related. Classical psychedelics act on serotonin 2A receptors and produce a profound, hours-long change in perception. Ashwagandha does not do that at any dose people take.
Same answer for most of the herbs people ask us about in the same breath. Kava, valerian, chamomile, lemon balm, St. John's wort, lion's mane, reishi, rhodiola: none of them are psychedelics. Some have real pharmacology worth respecting, and a few interact with prescription medications, which is a conversation for your prescriber. But none of them belong in the same paragraph as psilocybin.
DEFINITIONS
So what actually is a psychedelic?
The classical psychedelics are a fairly small group. In plain terms:
- Psilocybin — the compound in more than 200 species of mushrooms. This is the one furthest along in modern clinical research.
- Mescaline — from peyote and San Pedro cacti. Long history of ceremonial use, very little modern clinical trial work.
- DMT — found in a number of plants and, in ayahuasca, brewed with a second plant that keeps it orally active.
- LSD — semi-synthetic, derived from an ergot fungus. Made in a lab, not harvested.
- Ibogaine — from the iboga shrub. Studied mostly for opioid dependence. It carries real cardiac risk and is not a casual substance.
Two more get filed under "plant medicine" constantly and are not plants at all:
- MDMA is fully synthetic and is not a classical psychedelic. It is usually called an empathogen. It has been studied for PTSD, not depression.
- Ketamine is fully synthetic too. It is a dissociative anesthetic, first synthesized in 1962 and FDA-approved as an anesthetic since 1970. It is not a plant, not a psychedelic in the classical sense, and it is the only one of these you can legally receive in a clinic in Indiana today.
INDIANA LAW
What is legal in Indiana right now
Psilocybin, MDMA, DMT, mescaline, LSD and ibogaine are all Schedule I under federal law, which is the DEA's category for substances with no currently accepted medical use. Indiana has not created any exception to that. There is no legal psilocybin service center in Indiana, no legal ayahuasca ceremony, no legal ibogaine clinic, and no medical exemption you can apply for.
Indiana has done one notable thing, and it is worth understanding precisely, because it gets misreported.
Indiana funds psilocybin research. That is not the same as legalizing it.
In 2024 the Indiana General Assembly passed Senate Bill 139, creating the Therapeutic Psilocybin Research Fund. In 2026 the state directed $300,000 to Indiana University School of Medicine for a clinical trial in treatment-resistant depression and substance use disorder, with a focus on veterans and first responders. Participants receive a single dose alongside several weeks of psychotherapy.
That is a state-funded clinical trial. It is real and it matters. It does not make psilocybin available to you, your neighbor, or us. Anyone telling you Indiana "legalized mushrooms" is wrong, and if they are selling something, be careful.
What ketamine actually is in the legal picture
Ketamine sits in a different place entirely. It is Schedule III, FDA-approved as an anesthetic, and prescribed off label for depression, anxiety, PTSD and chronic pain. Off label prescribing is ordinary medicine, not a loophole, and it is how a great deal of psychiatry works.
That legal status is the whole reason a clinic like ours can exist in Greenwood while a psilocybin clinic cannot. If you want the longer version of that argument, we wrote it up in Indiana's only legal psychedelic.
THE NATIONAL PICTURE
What is actually moving nationally
Dated honestly, as of September 2026:
- Psilocybin, FDA track. Compass Pathways completed Phase 3 work on COMP360 for treatment-resistant depression, and in April 2026 the FDA granted a rolling NDA review along with a national priority voucher that shortens review time after filing. It is not approved. It is closer than any psychedelic has ever been.
- MDMA, FDA track. The FDA declined the first MDMA-assisted therapy application for PTSD in 2024. In August 2026 the company, now called Resilient Pharmaceuticals, refiled. It is not approved and there is no announced decision date.
- Oregon. The only fully operational state psilocybin services program in the country. Licensed centers, trained facilitators, adults 21 and over. Not a medical prescription model, and not open to out-of-state medical referrals in the way people assume.
- Colorado. Licensed healing centers under its own regulated framework, more recent and smaller than Oregon's.
- New Mexico. A medical model restricted to specific conditions, with implementation targeted for the end of 2027.
Notice what is not on that list. Indiana. And notice the shape of the whole thing: a lot of genuine progress, none of it available to an Indiana resident who needs help this month.
IF YOU ARE WAITING
A word about waiting
We talk to people who have decided to hold on until psilocybin is approved. Sometimes that is a reasonable call. Often it is a way of putting off a decision that is hard to make.
Nobody knows the approval date. Nobody knows what the label will say, which patients will qualify, how many certified sites will exist in Indiana in the first year, or what it will cost. If someone gives you a confident answer to any of those, they are guessing.
What we would say is this: the question is not which molecule is most exciting. The question is what is available to you now, whether it is a reasonable fit for your situation, and what you would be trading by waiting another year. That is a conversation, not a sales pitch, and it can end with us telling you this is not the right thing for you.
WHERE KETAMINE FITS
Where ketamine therapy fits
Ketamine therapy is not a plant medicine and we are not going to dress it up as one. It is a medical treatment delivered in a clinical setting under physician supervision, with an IV, monitoring, and a plan.
What it does share with the research on psilocybin is the shape of the thing: a small number of supervised sessions rather than a daily pill, an altered state that most people find meaningful, and a period afterward where what you do with the experience matters. That last part is why we built our integration program instead of just running infusions.
If you want the clinical detail, start with IV ketamine therapy. If you are comparing it against other options, we wrote an honest comparison of TMS, Spravato, ECT and IV ketamine, and a separate one on IV ketamine versus at-home ketamine. If you are a veteran or a first responder, this page is for you.
GET STARTED
If you are reading this because you are looking for something
Most people do not land on a page about plant medicine out of botanical curiosity. They land here because something has not worked and they are looking for a door that is still open.
If that is you, the useful next step is a free consult. It is about thirty minutes, it is with our team and not a call center, and the point of it is to find out whether ketamine therapy is a reasonable fit for your situation. If it is not, we will say so, and we will tell you what we would look at instead.

No. Psilocybin is Schedule I federally and Indiana has created no exception. The state funds a psilocybin clinical trial at Indiana University School of Medicine, which is research, not legal access.
Is ketamine a plant medicine?
No. Ketamine is a synthetic dissociative anesthetic, first made in 1962 and FDA-approved in 1970. It is legal, it is Schedule III, and it is prescribed off label for depression and other conditions.
Is ayahuasca legal in Indiana?
No. DMT is Schedule I. Narrow federal religious-use exemptions exist for specific churches and do not create general legal access in Indiana.
What is the closest legal option to a psychedelic experience in Indiana?
Physician-supervised IV ketamine therapy is the only legally available option in Indiana today.
