Four bottles of Dr. Sealy's "5 Ring Oil." (FIRE, WATER, EARTH, CRYSTAL) Includes a manual (electronic) on how to use it. Purchased from Masayo Koyeyama's online site around 2023. Used only a few times. Please check the photos for the remaining amount. Currently, there seems to be no prospect of the next shipment on the online site, and an announcement has been made that sales will end with the current stock. If you were interested, how about taking this opportunity? Thank you for your consideration. --- 1. FIRE (Fire) Regenerates and strengthens "DHEA (Dehydroepiandrosterone)." DHEA is the most important hormone for reviving and activating the endocrine system and suppressing stress. 2. WATER (Water) Helps balance "aldosterone." Aldosterone balances sodium and potassium in the blood. 3. EARTH (Earth) Aids in the regeneration of "calcitonin." Calcitonin is a hormone produced by the body. Essential for preventing and overcoming osteoporosis. Also, it reduces pain with a strength 40 to 60 times that of morphine. 4. CRYSTAL (Crystal) Suppresses the production of reactive oxygen species in the body. Reactive oxygen species damage cells and are said to be the cause of swelling, aging, and more than 200 major diseases. ---
