It was found that the corn seedlings were sparse, the unearthed corn seedlings were shrunk in the soil, and the stem base was swollen, the main roots and lateral roots were inhibited, and the stems and leaves were atrophied and deformed. Even if the corn seedlings that have been unearthed are short and deformed, the bottom of the corn is half-footed.

Herbal Extracts are concentrated forms of plant-derived compounds that are used for various medicinal and therapeutic purposes. These extracts are obtained by processing plants and isolating the active ingredients responsible for their beneficial effects.
There are several ways to classify herbal extracts based on their properties and applications. One common classification is based on the solvent used for extraction. Solvents like water, alcohol, and oil are commonly used to extract different types of compounds from plants. Water extracts, also known as herbal teas or infusions, are made by steeping herbs in hot water. These extracts are often used for their mild and soothing effects. Alcohol extracts, known as tinctures, are made by soaking herbs in alcohol or a mixture of alcohol and water. Tinctures are highly concentrated and are known for their long shelf life and fast-acting properties. Oil extracts, also called essential oils, are obtained through processes like steam distillation or cold-pressing. These extracts are highly concentrated and are used for their aromatic and therapeutic properties.
Another classification of herbal extracts is based on the part of the plant used for extraction. Some extracts are derived from the leaves, flowers, or stems of the plants, while others are obtained from the roots, bark, or seeds. Each part of the plant contains different types and concentrations of active compounds, which determine their specific effects. For example, leaf extracts are often used for their antioxidant and anti-inflammatory properties, while root extracts are known for their immune-boosting and energy-enhancing effects.
