Replied by Ted (Bangkok, Thailand)
Since lemons throughout the world have no standard size, I decided to reformulate something that people can use with some more consistency. In Thailand lemon is nonexistent, and lime is very small, compared to UK, U.S., and Europe for example. Apparently the farmers here can't sell the small ones, only the larger sizes are sent abroad. However the small size lime made an ideal remedy in the long run.
If the frothing is too much, add water first, then the lemon and baking soda. Do not remove the frothing, that was the mistake. Here is a more specific way of doing it to minimize the frothing:
1. Add water to 1/2 glass 2. Add 1/2 teaspoon of baking soda 3. Stir the solution well until baking soda dissolves itself. 4. Add 8 teaspoon of lime juice (has more vitamin C and works better for the phlebitis than the lemon one). However add slowly one teaspoon at a time and stir. Lemon is still o.k. and you can use it too.
Wait 5 minutes so the reaction can be completed. If not, the lime/lemon acid may cause a heartburn. Do not remove the frothing.
If it is not working for you, the body has lack of bicarbonates in which case sodium ascorbate vitamin C 500-1000 mg taken once a day and 1/4 teaspoon of baking soda twice a day is another remedy that has the same effect for the problems of phlebitis.
