Jay has never had a proper mentor, but has tested and researched the herb himself through trail-and-error

- Borage
- Broom
- Burdock
- Burnet - Red Spikeblub - x - They seemed to have helped a cat regain strength after being consumed, but it's not totally proven it was the cause of the plant
- Catmint
- Celandine
- Chamomile
- Chervil
- Chickweed
- Cobwebs
- Coltsfoot
- Comfrey
- Dandelion
- Death berries (yew) - Silence pine - x - Almost right after the flesh and pit of the berry was consumed the cat started foaming at the mouth, having trouble breathing, being unable to move around and started shaking; the effects eased and almost disapeared once the berry was vomited up
- Feverfew
- Goldenrod
- Honey
- Horsetail
- Juniper
- Lungwort
- Marigold
- Moss
- Poppy - Resting Rose - x (used in the previous post) - Only moments after four of the seeds were consumed, the cat felt into a very deep sleep (fewer seeds -would like be a lighter and shorter sleep, but more seeds could possibly be fatal according to Jay's theory)

- Ragwort
- Sticks
- Nettle
- Tansy
- Tormentil
- Thyme
- Yarrow - (White) Flyflower - x - The second it was consumed the patient vomited it and the contents of their stomach, it's not proven it was the cause of the plant, but couldn't really have been anything else
