If you understand herbs at all you know what will help the most are the herbs that work on the part of the body where the symptoms are occurring but also since our bodies are nothing but a bunch of cells and two major fluids (blood and lymph) it is important to keep those fluids clean - especially the lymph which is the body's main sewer system- ALSO OUR IMMUNE SYSTEM - and cleans away wastes from our bodies' cells and ideally transports them down to our kidneys and out into our urine.
The way to keep the lymph fluid clean is with the lymphatic herbs and with a clean diet that won't clog your lymphatic system/immune system.
I have brought on floaters myself by eating meat, dairy and refined grains together. which have little chance of being fully digested and expelled from the body, especially when eaten together. I got rid of them with an eyewash I made based on Dr. John Christopher's formulas using Eyebrite and Cayenne Pepper tincture. His Eyebrite formula is sold on Amazon and has Eyebrite, Bayberry Bark, Goldenseal, Red Raspberry Leaf and Cayenne Pepper in it. I got relief in hours after using it and only needed to use it a few days to get rid of the worst floaters I'd ever had. Study Dr. John Christopher's work and buy his books if you want to learn how to heal all ills. Dr. Linda Pages books are another good resource as is Dr Robert Morse.
To permanently rid ourselves of all chronic and degenerative conditions and "dis -eases", the answer is to get clean inside by detoxing our bodies. Doing a parasite cleanse is just part of it. A colon cleanse should be done at the same time as well as a liver cleanse using only herbs grown in Nature - not to be confused with man-made isolate vitamins and mineral supplements which the body can't fully recognize, digest, assimilate and eliminate but instead, the man-made supplements just stimulate at first but later enervate. Using whole herbs which the body sees as food, we can fully heal and get to the point where we no longer need them.
Besides the three cleanses above we need to work on dislodging and cleaning our lymphatic system which includes fluids in the eyes . That would entail taking herbs such as Dandelion and others - all the while supporting our adrenal glands which oversee our endocrine system and our kidneys which the metabolic wastes have to pass through if we are going to regain robust health. Lastly to do a cleanse we need a water rich raw plant based diet of mostly raw fruit and raw fruit-like vegetables with seeds and tender greens and to be dedicated and disciplined for 3-6 months while we detox our bodies and get rid of old wastes, dissolve tumors etc. Sometimes for those with "incurable" conditions, it takes longer but it is definitely doable. Nature has remedies for all our ills.
