The herb consists of the dried, 6 coarsely chopped (and usually peeled) rhizome of Acorus calamus (L. In animal studies, the herb 13 demonstrated spasmolytic and sedative effects, reduced spontaneous 14 stomach activity, and lowered the ulcer index (reduced the production of 15 gastric juices and acids). Calamus also has stomachic action due to the pres- 16 ence of bitter principles and the spasmolytic effect of its essential oil. In Germany, no official risk-to- 40 benefit assessment of calamus root has yet been published in any monograph. Natural R(+) 7 camphor is obtained by steam distilling the wood of the camphor tree, 8 the product of which is then purified by sublimation. The herb consists of the essential oil 49 distilled from the ripe seedlike fruit of Carum carvi L. Caraway seeds should be crushed immediately prior to use to prevent 41 unnecessary loss of the highly volatile essential oil. Its hot and 49 spicy fruit is best known as a spice, but is also used in medicine. The herb consists of the ripe, dried 3 fruit (without calyx) of Capsicum annuum L. Topical application of the herb initially induces erythema accom- 8 panied by sensations of pain and heat, followed by a phase of insensitivity 9 (reversible or irreversible deactivation of afferent fibers).
