Galenicals, also known as herbal preparations, are medicinal products derived from plants and plant materials. These preparations have been used for centuries in traditional medicine and are still relevant today. Understanding the definition of galenicals, the equipment used for extraction processes such as infusion, decoction, maceration, and percolation, as well as the methods of preparation for spirits, tinctures, and extracts is essential for their proper formulation and use.

1. Introduction
Galenicals are preparations derived from plants or plant materials used for their medicinal properties. They are an integral part of traditional medicine and have gained recognition in modern herbal medicine. Proper understanding of the definition of galenicals, the equipment used for extraction processes, and the methods of preparation is crucial for harnessing the therapeutic potential of these herbal products.
2. Definition of Galenicals
Galenicals are medicinal preparations obtained from plants and plant materials. They are formulated to extract the active constituents of herbs and utilize their therapeutic properties. Galenicals can be prepared using various extraction methods, including infusion, decoction, maceration, percolation, and others. These preparations may include herbal teas, tinctures, extracts, and spirits.
3. Equipment for Extraction Processes
3.1 Infusion
Infusion is the process of extracting the active constituents of plant materials by pouring hot water over them and allowing them to steep. The equipment required for infusion includes:
- Teapot or vessel: Used to hold the plant material and water during the infusion process.
- Strainer or sieve: Used to separate the liquid infusion from the plant material.
3.2 Decoction
Decoction involves simmering plant materials in water for a prolonged period to extract the active constituents. The equipment needed for decoction includes:
- Pot or vessel: Used to boil the plant materials in water.
- Heat source: Such as a stove or electric burner.
- Strainer or sieve: Used to separate the liquid decoction from the plant material.
3.3 Maceration
Maceration is the process of soaking plant materials in a solvent, typically alcohol or oil, to extract the active compounds. The equipment required for maceration includes:
- Glass container or jar: Used to hold the plant material and solvent during the maceration process.
- Strainer or filter: Used to separate the liquid macerate from the plant material.
3.4 Percolation
Percolation involves passing a solvent through a column containing the plant material to extract the desired constituents. The equipment needed for percolation includes:
- Percolator: A specialized glass or stainless steel vessel with a bottom outlet and a perforated plate or filter to hold the plant material.
- Solvent reservoir: Holds the solvent and allows it to flow through the percolator.
- Receiver vessel: Collects the liquid percolate.
4. Methods of Preparation
4.1 Spirits
Spirits are alcoholic preparations that extract the medicinal properties of plants. The process of preparing spirits involves macerating the plant material in alcohol for a specific period. After maceration, the liquid is filtered, and the resulting spirit is obtained. Spirits are commonly used as herbal remedies or as ingredients in other galenicals.
4.2 Tinctures
Tinctures are concentrated herbal preparations made by extracting the active constituents of plants using alcohol or a mixture of alcohol and water. The process of preparing tinctures involves macerating the plant material in the alcohol solvent for an extended period. After maceration, the liquid is strained and filtered to obtain the tincture, which is usually more potent than spirits.
4.3 Extracts
Extracts are concentrated preparations that contain high levels of active constituents obtained from plants. The process of preparing extracts typically involves percolation or other advanced extraction techniques. Extracts can be in liquid or solid form, such as dry powders or soft extracts. They are used in various forms, including capsules, tablets, and topical applications.
