You can sell the plants to Pricia for 850$ or you can use the red ginseng and get intelligence boost from the doc (that will give you many jades and a decent amount of silvers) but the most important to know about grinding is to go a specific area like the first area in estero park and move between that area and the next one back and forth using your keyboard. You do this enough times and you will see the little spots to start to gather on their own. You get to see all the plants in the same area as well. There is no need to run around the park searching for one or two spots. Just use your keyboard to change areas and you ll be fine. Here is a list of the boosts:
Doctor boosts (Intelligence = it will be present until you find 2,3 or 4 rare treasures such as jade and silver talismans)
Simple visit to doctor with 140 coins : intelligence boost for 2 rare treasures (armpit hump)
Eat Green Ginseng and go to doctor (-140 coins): intelligence boost for 3 rare treasures (ass hump) or quick boost
Eat Red Ginseng and go to doctor (-140 coins) : intelligence boost for 4 rare treasures (thigh sex) or quick boost
Pricia boosts (Awareness = When visiting a location, the shining spots will be multiple instead of one)
Jade Talisman : 30 seconds of awareness
Silver Talisman : 2 minutes of awareness
Gold Talisman : Infinite time of awareness until you find a gold one.
I hope this helps you out. Happy hunting!
