There are no studies showing that garlic is a kidney tonic, so there is no such thing as how to consume garlic as a kidney tonic. It is worth mentioning that the recently popular black garlic is made from fresh garlic, which is processed and fermented, and also does not have the effect of tonifying the kidneys. From the perspective of Chinese medicine, garlic is a dual-use food, pungent and warm in nature, and belongs to the spleen, stomach and lung meridians. It is used to treat scabies, snake and insect bites, carbuncles and swelling, diarrhea, dysentery and malaria. After roasting black, garlic is also good for cold pain in the stomach and abdomen and stagnant diet. Modern research shows that the health benefits of garlic are mainly related to allicin, which can play an antibacterial, antiviral and antiprotozoal role, and has an adjuvant effect on patients with tuberculosis or post-chemotherapy Aspergillus infection; in addition, it can also help lower blood lipids, prevent atherosclerosis and inhibit platelet aggregation. People with kidney deficiency can consume some foods with kidney tonic effects, such as mutton, beef whip, walnut meat, mulberry, yam, etc.; they can also take Chinese herbs with kidney tonic and essence effects, such as Shu Di Huang, Cuscuta, Lycium, Epimedium, etc. or use Chinese medicines, such as Liu Wei Di Huang Wan, Jin Kui Kidney Qi Wan, Zuo Gui Wan, etc., after the doctor’s identification. It is also recommended that people with kidney deficiency avoid overindulgence, maintain emotional stability, and exercise moderately to enhance physical fitness.
