GrassRx is the world's first prescription-grade outdoor experience platform. Your licensed physician identifies the exact field, meadow, or patch of grass your body needs — and we handle everything from there.
* GrassRx prescriptions are legally binding in 3 states. Results may include: feeling calmer, seeing a butterfly.
GrassRx™
1 Field · Twice Weekly
Our evidence-adjacent four-step system ensures you receive the correct field for your unique biometric grass profile.
Complete our 47-question survey about your feelings toward soil, humidity preferences, and comfort with insects.
A board-certified GrassRx provider reviews your file and cross-references it against our proprietary FieldMatch™ database.
You receive a laminated prescription card with GPS coordinates, recommended footwear, and ideal standing posture diagram.
Proceed to the designated field. Stand there. Our app monitors compliance via satellite. Minimum 20 minutes recommended.
GrassRx combines precision medicine, geolocation, and an enormous database of outdoor spaces to deliver truly personalized outdoor standing experiences.
Our AI cross-references your biometric data with 50,000 catalogued fields to find grass with the optimal blade density, moisture content, and ambient bird-chirp frequency for your condition.
Our app verifies you are standing in the prescribed field and not, for example, a parking lot. Wayward patients receive a gentle push notification and a note of concern from their prescriber.
Receive automated reminders for your field visits. Prescriptions include morning vs. afternoon guidance, optimal cloud-cover windows, and dew-point contraindications.
Track your wellness progress with our proprietary GrassScore™ metric, combining self-reported calmness, shoe cleanliness upon return, and number of clouds observed.
Physicians get a streamlined dashboard to write, renew, and refill field prescriptions. Includes a map view, seasonal field availability, and one-click "Just Go Outside" orders.
Premium subscribers receive a dedicated Field Concierge who scouts your assigned location, removes large sticks, and leaves a tasteful flag marking your ideal standing position.
Thousands of patients have received their GrassRx prescription and gone on to stand in an appropriate field. Here's what some of them had to say afterward.
"My doctor told me I needed to stand in a field twice a week. I thought it was a joke. It wasn't. The field was beautiful. I cried. My back feels the same but my soul is marginally better."
Derek B.
Prescribed: Rolling Meadow, Vermont
"At first I pushed back. I said 'Doctor, I have anxiety, not a grass deficiency.' She said 'Linda, I'm writing you a prescription.' I stood in that field for 22 minutes. I haven't called HR once since."
Linda K.
Prescribed: Sunny Clearing, Ohio
"Four stars because the field had a slight incline they didn't mention. Otherwise the experience was transcendent. The laminated prescription card is now framed in my hallway."
Marcus R.
Prescribed: Coastal Grassland, Maine

Our founding team combines decades of clinical expertise, software engineering, and a sincere personal appreciation for grass.
CEO & Chief Prescriber
Former hospitalist. Discovered the therapeutic potential of grass after getting lost at a conference in Portland. Never looked back.
CTO & Head of Satellite Ops
Ex-Google Maps. Left to pursue something more meaningful. Built FieldMatch™ in 11 days. Has not been in a field personally.
Chief Grass Officer
Environmental botanist. Developed the GrassScore™ rubric. Maintains that bluegrass and fescue have meaningfully different therapeutic profiles and will discuss this at length.
VP of Field Relations
Manages relationships with field owners, municipalities, and one very understanding farmer in Nebraska who lets us use his back 40 for beta testing.
Our landmark study involving 47 participants, three fields, and one very windy afternoon in April is currently under review at a journal we are not at liberty to name. Results were promising. Or at least not discouraging.
Download Pre-Print (137 pages, mostly appendix)No. We have submitted 14 pre-authorization requests across 6 insurers. Three of them replied. We remain optimistic.
GrassRx has a network of licensed telehealth prescribers. A 15-minute consultation is all it takes to receive your official field assignment. Most consultations end with the prescriber also recommending they go stand outside.
This is an off-label usage of GrassRx. Our prescriptions specify standing posture. That said, we are not the police. A seated field experience is better than no field experience. We ask that you at least sit upright.
Contact your Field Concierge (Pro/Enterprise) or our support team. We will identify a substitute field within your biometric compatibility range. Note: a substitute field is not the same as your primary field and may produce slightly different results.
GrassRx operates in a regulatory space the FDA has not yet formally defined. We prefer the term "FDA-Adjacent." We have a meeting scheduled. It was rescheduled. We are working on scheduling a new meeting.
Join over 12,000 patients who have received a legitimate, physician-issued prescription to go stand in a specific outdoor location. Your body will thank you. Probably.
