this isn't really something to "dabble" in. If you need someone to not only tell you what plants to plant, but also how to use them, what you should do is take a class It's too easy to hurt or even kill someone with this if you don't know what you are doing. There are thousands of medicinal plants that can grow in zone 5 (that's also my zone) but what specifically are you wanting to medicate? If you want a really useful book, get "the herbal PDR", it will at least give you how they interact with other herbs and medications.

Taiguey guaitiaonagu!

Myname is Manny and I am so happy to be included in this group.

I remember my grandmother in Boriken always had plants for different ailments. Some are commonly known, like aloe to treat burns and insect bites. She also had "aji" which she mixed with oregano oil (which she did herself). This is and intense ointment for ailing joints due to arthritis. Things like chamomile, lavender, salvia, citrus trees, "tuna" cactus, guayaba (guava), guanabana (soursop). She even used roses for baths and to infuse teas. 

But most of these don't grow in the northern states.

You can find some items like oils and herbs in the local market, and I use them to treat my arthritis.

I miss all that knowledge from our elders. Wish I had had more time with them to learn more.

Jajom.

Isn't that the way, Manuel? Too bad so many people don't pay attention till it's almost too late! But it's no different than any other generation (youth is wasted on the young!) lol
