The best way to use Cosmic Serums is to allow them to work on their own. VK with Cosmic Serums have wisdom to know where they need to work on.
For example ALL CLEAR SERUM , one might intend for constipation but when its taken without intention, it will clear negativity at multiple levels.
Same way for FLAB DOWN SERUM, though it gets favourite of people who want to manage their weight. It works at multiple level not just thyroid. Thyroid being one of the place where energies in FDS work. So best is to allow it to work on its own.
However if there is an emergency, like constipation or gas causing stomach ache, we can rub VK specially on abdomen with chanting of ALL CLEAR SERUM to take care of such pain on priority.
Same way we can send ALL CLEAR SERUM specifically to events or situations which are stuck or not moving. For example pending work or Court cases or to remove clutter from homes.
When i charge water or use other methods to send energies through VK , I keep the intention heal NOW FOREVER rather than targeting any specific organ, thus allowing it to work on multiple levels i do not know where the problems are arising from.
