James Loucks, of Indianapolis, Indiana, registered a Patent for his "Hair Restorative" in 1864 (Patent #41,076). The following is the recipe from the letters of patent:
I compound my hair-restorative of the following substances, viz: olive or sweet oil, tincture of Lobelia inflata, Cypripedium pubescens, and Agrimonia Eupatoria. The tinctures of Lobelia inflata, Cypripedium pubescens, and Agrimonia Eupatoria I make by digesting the ground seed in alcohol in the proportion of one pound of the seeds of each separately digested in one and one-half gallon of ninety-five per cent. alcohol for any length of time sufficient to extract the strength of the seed--say from two to four weeks. Of these tinctures or extracts I use in compounding my hair-restorative two and one-half ounces lobelia, ten drops cypripedium, ten drops agrimonia, and two ounces of the sweet or olive oil.
