Yeast infection or candidiasis is quite a common discomfort suffered by thousands of people everywhere, and due to their intimate secret, mostly suffered in silence! It is therefore important to find natural and safe methods to both alleviate and discontinue its reign over the silent multitude. Common causes of yeast infection include:
1) Antibiotics and their over-use
2) Birth control pills (presumably)
3) Hormonal changes
4) Chlorine in drinking water
5) High levels of iron, lead, mercury and aluminium
6) Anti-inflammatory drugs, and many more!

So, in essence, to cure your yeast infection you should focus on:
1) Avoiding unnecessary antibiotic medication
2) Filtering your drinking water
3) Avoiding tight fitting clothes (to ensure proper aeration)
4) Not taking birth control pills (if at all possible).

In general, one should focus on good personal hygiene and avoid douching at all times - the vagina self-cleans, thereby making douching unnecessary. Douching actually upsets the delicate balance between good and bad bacteria in the vaginal ecosystem and can be really harmful. Also, do not wipe from back to front after going to the toilet, as yeast and bacteria generaly occur in the intestine, and therefore might be transferred to the vaginal area.

Remember: yeast occurs naturally in any healthy vagina, but might increase due to changes in acidity and other common causes as mentioned before. Strictly avoid taking antibiotics to cure your yeast infection, especially if it needs to be applied to the vaginal area directly, as these will most assuredly diminish your prevalent yeast cultures totally! The idea is to cure the condition and the cause as safely and naturally as possible.
