I buy GREEK LIVE yoghurt. Eaten from a spoon when I fancy it ;-). Also applied into the vagina in the years prior to being diagnosed with VA, the idea being to cleanse the digestive system from top to bottom.
The GREEK has 'live' in red on the carton. No additives. I also eat Waitrose 'live' with hazelnuts in YUM ;-)
It worked after in the 1990s I had emergency surgery = intense thrush [appendicetomy].
. My Aunt had brain surgery in the 1980s and used it following surgery, as her digestive system was wrecked. She had trigenimal neuralgia and underwent 2 lots of surgery to get rid of the intense, shooting pains; 15 years apart.
