The veins in my sister’s left leg are practically non existent. Her big Toe was amputated and dr. said leg is next. She is diabetic from 3 years of age and now 49. She is desperate to strengthen her veins or loosen plaque without a heart attack!

1. Here is a great video on how a change in diet may help. This is on high blood pressure, but should apply just as much.

2. Lysine, Proline and Vitamin C are reported to help clear vessels.
Nattokinase enzyme and Serripeptase are said to help clear vessels too. I can attest to their usefulness for my lyme, which clogs vessels too.
They have given me sensations back to my lower legs area but, if I stop the ability to feel goes away again.

Research those.

CONTACT will give quicker results than Remote, try that.

Starting alternative treatments when it is almost too late, often is not going to help and if not successful please don't blame Spooky for not saving a crisis.
When it is Crisis time, it requires Dramatic methods.
What can one do to restore and rebuild the body? PURE food without Pesticides, GMOs or other garbage "food."
Good luck!

3. I second what John has mentioned, especially try the contact method (circulatory stasis program), which has worked for me on my circulation issues (lower body). If I were you, I would make a beet and pomengranate juice for your sister to drink 3 - 4 times a day. Excellent for clearing and widening blood vessels as well as increasing blood flow. Cut out all dairy and meat for a while.

You may also consider liquid DMSO. As a vasodilator, DMSO enlarges small blood vessels, increasing the circulation in an area.

If you sister can bounce up and down a mini trampoline, I strongly suggest getting her a rebounder. You can pick up a used cheap one off Craigslist.

4. Also consider
Venous Insufficiency KHZ - needs 100% offset applied to OUT1 & OUT2 in contact mode.
Varicose Venis KHZ - needs 100% offset applied to OUT1 & OUT2 in contact mode.
