I wanted to re-post it since you have mentioned that you are having trouble with your finger tips, and the poster quoted in the post mentions how it had helped them with their finger tips.
I know how you feel about the expense, though. For $36 including shipping and handling, you would hope that you would get a little larger jar. I've even written to the company asking them to make a larger jar, but they never responded. They also don't send any follow up emails, such as "Doctor's Defense 2 for 1 special!" Unless you re-order, you'll never hear from them again.
If it's any consolation, I found that as my skin got healthier, I needed to use the Doctor's Defense less and less. I'm now down to where I haven't needed to use it for over a week. Also, the expense doesn't seem so bad when I think about how much money I've spent on doctors and cortisone cremes. Doctors are expensive, and Doctors Defense works so much better than any cortisone creme.
Because the Doctors Defense is so expensive, though, I'm very curious about whether the Blue Poppy Eczema Ointment another person mentioned is as effective since it also has Chinese herbs in it. It's only $10. I haven't compared the formulas to see if they are the same or similar, but it's something to consider experimenting with.
