Relieves morning sickness during pregnancy.
Speeds healing of skin ulcers, wounds, or burns.
Treats gastritis and ulcerative colitis.

Roman Chamomile seeds produce a thick, evergreen perennial herb plant that is very versatile and lovely. Forms a 6 inch mat of sweetly scented, parsley-like, bright green foliage, and it produces tiny, white and yellow daisy-like blooms in the late spring. An herbal flowering carpet comes to life!
This herbal carpet can even be used as a lawn substitute. This species is grown for the famous British Chamomile lawns.
Roman Chamomile plants may deteriorate in very cold or wet winters, but they will most likely recover. Harvest chamomile flowers when they are first fully opened. Use them fresh or freeze them for later use. Another benefit is that the flowers are used in herbal teas and are said to have medicinal properties.
Often used as a ground cover, Roman Chamomile holds soil in place even on slopes, it spreads to fill in gaps, and it blocks out most weeds. It can be mowed (after flowering and set the mower on the highest setting), and it tolerates light foot traffic. This ground cover is unique, aromatic, attractive and is well-suited for covering large areas and can be started by sowing the herb seeds ( Sow on cultivated soil. Sowing Rate: Approximately 5,000 seeds covers 100 square feet. Average Germ Time: 7 - 10 days. Keep moist until germination. Depth: Surface sow, cover lightly with peat moss. )
Attracts honeybees and birds. Young leaves and flowers can be gathered to make a calming tea, both fresh and dried.
