I just found one, called a bone-building tea. When I was in my late 50's, I had a bone scan test done and they found I had low bone density. I was diagnosed with Osteopenia with a test score almost high enough to be Osteoporosis. So I take medication, as well as calcium and vitamin D supplements. Wish I had known earlier that I had this problem. I already take the Nettle and Red Clover in my tea...will have to look for the other ingredients.
Bone-Building Tea
Oatstraw
Nettle leaf
Dandelion leaf
Raspberry leaf
Red Clover, flowering tops
Horsetail shoots
1. Boil one quart of water
2. Turn off the heat. Blend herbs in equal parts.
3. Add 4 tablespoons of the herb blend
4. Cover and steep 30 to 60 minutes, then strain. Drink 3 to 4 cups a day.

While it may be good for you it doesn't sound very tasty.
I don't think I have ever seen a tea with Horsetail shoots, Do you think they mean the fresh new shoots in the spring? Do you even have them there? they like to grow along river banks or creeks. Do you even have any of them (creeks& rivers) left after this drought?

Don't have any around here and I don't know much about them...I was going to ask someone at the health food store today, but it had just changed ownership and I never found anyone knowledgeable to ask. I did see some Horsetail tea in bags, but don't know if that could be the same thing...or not!

After looking into it, it appears that horsetail shoots are just some fresh growth on horsetail plants.

I looked at the photo and it was not the plant I was thinking of. the plant I was thinking of was horsetail rush.
I think the plant you showed grows here as a weed , I do know I pull it . I will need to study further
Love learning something new
