Most of the parts will fall off because they are no longer needed. Stamen and petals will fall off (I cannot think of a plant where this doesn't happen). Sepals may or may not fall off. Think of a strawberry or a tomato. The leafy structures on these fruit are actually the remnants of the sepals.
Some pills are completely water soluble and therefore would dissolve in water faster than other liquids which are a mixture of water with other compounds. In some cases the sugar in Kool Aid and in Cola may cause some inhibition of the dissolution process.
Some health professionals recommend 50mg zinc lozenges, which can be purchased at most health food stores as well as many drugstores. Let the lozenge dissolve in the mouth three times a day. Other recommendations are for lower potency lozenges of 5-10 mg which you can suck on or dissolve against your ulcer four or five times a day. Another option is to dissolve one or two zinc lozenges in half a cup of hydrogen peroxide a half cup water and gargle with the mixture several time a day.
