Most rectal itching is due to pinworms and it is very common to have both parasite and fungal infections at the same time. This is a function of the overall imbalance of the digestive flora and suppression of normal immune system function. For that, I recommend Agrisept-L at 10-15 drops, twice a day in water or juice. A little bit of grapefruit juice helps to negate the bitterness of the grapefruit seed extract in the Agrisept-L. Additionally, I recommend Morinda Supreme, 2 scoops, twice a day in water.
Thrush can be a little tricky depending on how ingrained the fungal candida is and which layer it is binding to in the tissues. Iodine applied topically can help. Some people have used oregano oil, tea tree oil, or even the Agrisept-L successfully for this, also. With fungal candida and aging, you can expect to see a reduction in the absorption of iodine, so the iodine may benefit you in other ways.
Obviously, doing a good candida elimination program can be helpful for both of these conditions, as a systemic approach is almost entirely necessary at the same time. I recommend the McCombs Plan - http://www.mccombsplan.com
- for reverting the fungal candida back into its normal yeast form and boosting the immune system to get rid of the excess yeast.
