As for a link, I doubt you'll find one. My info comes from text. Via the internet, you're likely to wind up with large promises, but long legalese disclaimors in leu of info when you click on links.
I suggest you start with a good primer, such as The Herb Book, by John Lust ©December, 1974
Also, find an elderly person, especially someone who immigrated circa WWI to help yu identify particular herbs. An elderly native Amercan IN GOOD STANDING within his or her tribe is also a good idea.
Due to lawsuits, herbalists are paranoid about what recipes we publish via the internet, which is a huge loss to the human race and a huge gain to the pharmacutical companies. I've got a databse all made up....had it for 5 years now, which I'm afraid to publish...and it does NOT contain pics as were originally planned for plant recognition. The recognition part is why I recommend an elderly person to help you. Someone who knows herbs. There's still one in almost every neighborhood.
Good luck. Dogged perserverance helps.
