Plant Description Hawthorn is a common thorny shrub that grows up to five feet tall on hillsides and in sunny wooded areas throughout the world. In May its flowers bloom, but although hawthorn is in the same botanical family as roses, the flowers are not fragrant. They grow in small clusters, and are white, red, or pink. Small berries, called haws, sprout after the flowers. They are usually red when ripe, but they may also be black.
Hawthorn leaves are shiny and grow in a variety of shapes and sizes.
These parts are dried and then made into powder. In liquid forms of botanicals, the alcohol and water create a more digestible form. Available Forms Hawthorn comes in capsules, tinctures, standardized fluid extracts, or solid extracts. You can also make a bitter-tasting tea from dried cut hawthorn leaves, flowers, and berries. How to Take It Look for standardized hawthorn products.
