This section looks at why shipwrecks are important and how they become time capsules for archeologists.
Mosses when growing in tufts should be gathered just before the capsules have become brown, divided into small flat portions, and pressed lightly in drying paper.
The whole of the operation must, of course, be completed in the few days - five to ten - during which the capsules are capable of yielding the drug: A cold wind or a chilly atmosphere at the time of collection lessens the yield, and rain washes the opium off the capsules.
Herbal preparations for holistic health care are available in capsules, oils, sprays, syrups, salves and tinctures.
Other forms of the herb are tablets, capsules, teas and raw root form.
