Corn gluten meal is a by-product of wet grinding corn processing. It is traditionally used as animal feed, but it can also be used for other purposes. For example, corn gluten meal is used as natural herbicide and plant food in organic horticulture, and corn gluten is often referred to as weed and feed garden adjuvant. Interestingly, corn gluten meal may also prove to be a home treatment for toenail fungi.

Corn gluten meal, a by-product of corn, has high protein content and is powdery. It can be used as a supplementary source of animal protein, including cats and dogs. Corn gluten meal is commonly used in organic gardening. It provides an option for those who want to slow or stop the growth of weeds without using toxic substances. This also increases soil nutrients, which may help promote the growth of ideal plants. There are several different ways to use corn gluten meal in the garden. One can spread the unprocessed powder throughout the garden by hand or through a manual planter. In this case, the corn gluten meal powder is applied directly to the soil instead of the top of the mulch. One can also use a spreader to spread granular corn gluten meal powder in the garden, or mix it with water to make a paste to prevent weeds from germinating while waiting for plants to grow. If it is used in the form of granules, it can also be spread by hand to increase soil nutrients and prevent weeds from growing. Corn gluten meal will weaken the ability of weeds to form roots after germination. Basically, the seeds dry as soon as they are opened. This leads to the formation of a bud without the root growth on which weeds depend. However, its concentration does not adversely affect a person's ripening or transplanted plants. That's why it turns out to be a herbicide and a plant food. Interestingly, some people claim that this product is also useful in family therapy. For example, some people use it as a medicine to treat toenail fungi. One usually adds water to corn gluten meal and leaves it standing for about an hour. One can then add warm water to the mixture and soak it for one to two hours. Although reuse may be necessary, some claim it is an effective measure to prevent toenail fungi.
