1. Introduction

Nettle, a plant with a long history of use in traditional medicine and various applications, has attracted significant attention in recent years. The extraction of its leaf extract using the natural wood log method is an interesting and potentially valuable approach. Nettle leaves are rich in a variety of bioactive compounds, such as flavonoids, phenolic acids, and minerals. These compounds endow nettle with properties like antioxidant, anti - inflammatory, and diuretic activities.

The natural wood log method offers a more "natural" and potentially sustainable way to extract these valuable components from nettle leaves compared to some modern chemical extraction methods. This method may also preserve the integrity of the bioactive compounds better, leading to a higher - quality extract.

2. The Natural Wood Log Method: Process

2.1. Preparation of Materials

1. Selection of Nettle Leaves:

• First, it is crucial to choose fresh, healthy nettle leaves. Leaves that are free from diseases, pests, and signs of withering should be selected.
• The time of collection also matters. Generally, nettle leaves are best collected in the morning when their nutrient content is relatively high.

• Natural, untreated wood logs are preferred. Different types of wood may have different effects on the extraction process. For example, hardwoods like oak or beech may be more suitable due to their density and chemical stability.
• The size of the wood logs should be appropriate. They should be large enough to hold a sufficient amount of nettle leaves during the extraction process but not too large to be difficult to handle.

2.2. The Extraction Procedure

1. Layering:

• Begin by placing a layer of nettle leaves on the bottom of the wood log. The layer should be spread evenly to ensure good contact with the wood surface.
• Then, repeat the process by adding another layer of nettle leaves on top of the first layer. The thickness of each layer can be adjusted according to the amount of leaves available and the size of the wood log.

• After layering, gently compress the nettle leaves. This can be done using a wooden plank or other suitable tools. The purpose of compression is to increase the contact area between the leaves and the wood log, facilitating the extraction process.
• However, be careful not to over - compress, as this may damage the leaves and affect the extraction efficiency.

• Place the wood log with the layered and compressed nettle leaves in a suitable environment. The temperature and humidity of the environment play important roles. A relatively warm and humid environment may promote the extraction process. For example, a temperature range of 20 - 30°C and a humidity level of 60 - 70% can be considered.
• During the incubation period, which may last for several days to a few weeks depending on various factors such as the type of nettle leaves and the environmental conditions, the bioactive compounds in the nettle leaves gradually migrate into the wood log.

• After the incubation period, the extract can be collected. This can be done by carefully removing the nettle leaves from the wood log.
• The extract may be in the form of a liquid or a semi - solid residue on the surface of the wood log. It can be scraped off or collected using appropriate tools.

3. Benefits of the Natural Wood Log Method

3.1. Preservation of Bioactive Compounds

One of the major benefits of the natural wood log method is the excellent preservation of bioactive compounds.

• Compared to some harsh chemical extraction methods that may use strong solvents or high temperatures, this method is relatively gentle. The natural wood log provides a stable and porous environment for the nettle leaves, allowing the bioactive compounds to be released gradually without being damaged or denatured.
• For example, flavonoids, which are sensitive to heat and certain chemicals, can maintain their antioxidant activity better during the extraction process using the natural wood log method.

3.2. Sustainability

1. Renewable Resources:

• Both nettle plants and wood logs are renewable resources. Nettle can be easily grown in many regions, and proper harvesting can ensure its continuous supply. Wood logs, if sourced from sustainably managed forests, also represent a sustainable option.
• Using renewable resources in the extraction process is in line with the principles of sustainable development, reducing the dependence on non - renewable resources such as some synthetic chemicals used in other extraction methods.

• The natural wood log method generally has a lower environmental impact compared to some industrial - scale chemical extraction processes. There is no need for large - scale use of toxic solvents or complex waste treatment processes.
• The by - products of the extraction process, such as the used nettle leaves and the wood log after extraction, can be more easily recycled or composted, further reducing environmental pollution.
