"Peppermint or menthol preparations are first of all irreplaceable in local anaesthetics, as well as for the relief of inflammatory processes which are so common among the beginner-yogis. Most of the pains of the yogis are connected with the inflamed condition of the nerve centers and glands because the channels of the nerves are closely connected with the glands. Therefore, the common “migrenstift” (migraine stick) is very useful, as well as applications of Baume Bengué, which contains a large amount of menthol. This has been proved by personal experience.
