Garlic bulb (Allium sativum) has a long history of use in various traditional medicine systems, including Ayurveda, Traditional Chinese Medicine, and Western herbalism. Traditionally, garlic has been valued for its purported ability to support the immune system, promote cardiovascular health, and improve vitality. Its use for the glandular system is less direct, but in traditional contexts, it has sometimes been used to promote the health of organs like the thyroid and adrenal glands, largely due to its general effects on metabolism and immunity.

Scientific studies have validated some of garlic’s effects, particularly its antimicrobial, cardiovascular, and immune-modulating properties, but there is limited direct scientific evidence linking garlic specifically to support of the glandular (endocrine) system as a whole. Some preliminary studies suggest that garlic may influence certain hormones or glandular functions, but the data are not robust or consistent enough to make a strong scientific claim. Most modern support for garlic’s use with the glandular system is extrapolated from its general health-promoting effects rather than direct evidence. Thus, its use in this context is primarily justified by tradition rather than strong scientific validation.
