The excessive use of garlick in cookery, may produce head-ache, flatulence, fetid breath, thirst, inflammations, fevers, and bloody piles.

ALLIUM CEPA, L. or Cepa vulgaris, Tt. Onions. Have the same properties as garlick, but weaker. Very useful as food in dropsies and suppressed urine. Onions correct the taste of fish, and can cure the bad effects produced by bad fish, salt, smoked, or putrid. They promote secretions and excite appetite. Their excess produces flatulence, thirst, head-ache, bad dreams, and may derange the central functions. Externally, they form good cataplasms for suppurating tumors. Raw onions can only suit strong stomachs, they render the breath offensive. When boiled or stewed, they are palatable and healthy. The ancients thought that onions and garlic could cure or prevent the plague. The A. porrum or Leeks, have the same qualities and uses, they are still milder than onions: both roots and leaves used.
