So easy to grow that I understand why it has been declared a weed throughout the world.

Caltrop strike easily from seed but as they have 'staggered' germination you must be careful not to toss out the potting mix on the garden once you have transplanted a few, as some seed will germinate two years later.

While there seem to be no side effects at all from use of Caltrop because it stimulates the bodies natural hormone producing facility and does not provide hormone to the body, it should be used with common sense as it does demonstrate a noticeable effect on both men and women.
