| Maceration is the only feasible method of producing a tincture from an unorganized drug such as gum benzoin or propolis resin. |
| You may try a strong ethereal or alcoholic solution of benzoin, tolu, storax, olibanum or labdanum. |
| These included balsam, musk, benzoin, aloeswood, ginger, muslin, thoroughbred Arabian horses, and Chinese porcelain. |
| Typical examples are aromatic ketones such as acetophenone, benzophenone, benzoin ethyl ether and benzyl dimethyl ketal. |
| The light oil contains the most hydride of benzoyl, and the heavy oil the most benzoin. |
| When the mixture begins to cool, add twelve drops of lemon juice and six drops of tincture of benzoin, while still continuing to stir. |
