First of all, touch some of it to your lips. If there is a sigificant tingling/numbness then the plants may have been exposed to pesticides, especially malathion.  If such is not the case, then start very slowly with perhaps 1/8 to 1/4 teaspoon of the extract (assuming that you followed the instructions on mixing it 50/50 with vodka or apple cider vinegar.  Put it under your tongue and keep it there for a few minutes and then wash it down with a strong healthy juice such as 100% Concorde grape, pomegranate or blueberry juice.

You may experience nothing at all initially, as happens with many people including myself.  On the other hand, some people have a bit of loose stool (and sometimes diarrhea), nausea and possiblly a mild headache - all of which are best avoided by making sure that you filter the extract very well and start with very small amounts.  If you have no such side effects, then work your way up slowly to larger doses as indicated in the instructions. 

If you are using the oleander extract against cancer, you may also feel some initial pain at the tumor location(s) as the oleander and enhanced immune system begins to do its work.  If so, that will pass in time.

Now, insofar as beneficial side effects, they may include increased stamiina and energy, increased male libido, faster hair and nail growth and diminished thinning hair,   Combined with a healthy diet and active lifestyle, you may find you are able to control any diabetes (if you have it) without relying on mainstream drugss.  Some even report a healthier appetite - meaning eating more sensibly and gaining weight when one is underweight or losing it when overweight and less cravings for sweets.

Keep us posted on your own experience.

All the best,
