Salt-tolerant plants (also called halophytes) can grow in saline soil or directly in salt water (e.g. along coasts). For centuries, these plants have been used in folk medicine, and among other things they are believed to have pain-relieving and anti-inflammatory effect. Even though experiments have already investigated halophytes as a pain relieving substance, the mechanisms in relation to pain and/or itch are still unknown. Therefore, the investigators wish to investigate whether halophyte-based cream applied to the skin can reduce itch applied by means of small needles from the plant mucuna pruriens (also called cowhage) or by histamine (an itch-evoking substance formed in the human body). Further, the investigators wishes to investigate whether long-term application of halophyte-based cream has a pain-relieving effect on heat/cold and pinprick stimulations.
