Quick Answers
Corn husks have many uses, both practical and decorative. They can be used to wrap and steam tamales, make dolls, create wreaths and other crafts, start fires, and more. While not as nutritious as the corn itself, corn husks do have some health benefits when consumed as tea or supplement. Overall, corn husks are very versatile and have value beyond just being discarded.
What are corn husks?
Corn husks are the thin, papery outer leaves that surround an ear of corn. They help protect the corn kernels while they grow. The husks are made up of cellulose fibers and contain small amounts of protein, vitamins, and minerals.
Fresh corn husks are bright green in color at first. As the ear of corn matures and dries, the husks become dry and yellow or brown. Once the ear is harvested, the husks are removed and typically discarded or composted. However, corn husks can have many uses beyond the cornfield.
Parts of the corn husk
Each corn husk consists of several distinct parts:
– The flap is the widest outermost layer that folds over and covers the inner husks.
– The blade is the thin papery sheath just under the flap. This is the part most commonly used.
– The innermost layer is called the silk. It has a finer, more textured surface and is lighter in color.
– At the base of the husk is the corncob with the corn kernels attached.
Composition
The primary component of corn husks is cellulose, making them tough and durable. They also contain very small amounts of:
– Protein: 1-2%
– Fat: 0.3-0.8%
– Fiber: 2-3.5%
– Ash: 0.5-0.9%
– Vitamin C: Traces
– Thiamine (Vitamin B1): Traces
The exact nutrition can vary slightly depending on the variety of corn. But overall, corn husks have very little food value, which is why they are usually discarded. But they still have many uses which take advantage of their physical properties rather than nutritional value.
Common Uses for Corn Husks
Thanks to their tough, flexible, water-resistant properties, corn husks have served many purposes across different cultures throughout history. Here are some of the most common uses:
Cooking
One of the oldest and most ubiquitous uses of corn husks is as a wrapper for steaming or baking foods. Specific examples include:
– **Tamales** – In Latin American cuisine, husks are used to wrap balls of masa dough stuffed with savory fillings to make tamales. The husks allow the tamales to steam perfectly and impart a subtle sweetness.
– **Pasteles** – In Puerto Rican cuisine, husks wrap seasoned smashed plantain or root vegetable dough into pasteles.
– **Fish or meat baking** – Husks can cover fish, chicken, pork, or other meats while baking or steaming to keep them moist.
– **Herbal medicine** – Corn husks are used in herbal medicine products and to make herbal teas.
Arts and Crafts
The rustic look and texture of corn husks make them great for arts, crafts, and decorations:
– **Corn husk dolls** – A traditional handcrafted toy made by tying dried husks into the shape of a doll or animal.
– **Wreaths and flowers** – Dried husks can be fashioned into decorative wreaths, wall hangings, flowers, and more.
– **Baskets** – Weaving dried husks creates sturdy baskets and containers.
– **Packing material** – The shock-absorbing properties of husks work well for cushioning fragile items.
Kindling
The dry papery material of corn husks ignites quickly and easily, making it useful kindling for starting fires. This works best with dry husks.
Fuel
In areas where corn is grown, dried corn husks may be used as a biomass fuel source. The husks can be compacted and burned directly for heat or gasified to produce syngas.
Fibrous Additive
When processed, the cellulose fibers of corn husks have uses as an additive or filler material:
– **Building materials** – Corn husk fibers can strengthen composite wood products like particleboard.
– **Textiles** – The fibers can blend with fabrics like cotton to make textiles.
– **Packing materials** – Much like straw, the husk fiber makes decent packing material.
– **Industrial processes** – Corn husks may be able to replace asbestos fibers in some industrial applications.
Compost
The fibers and nutrients in corn husks can enrich garden soil when composted. However, because the husks are slow to break down, they should be shredded before adding to compost.
Livestock Feed
While not highly nutritious, corn husks can serve as roughage, providing fiber to aid digestion in cattle, pigs, and other livestock. The husks pass through undigested but help move food through the gut.
Seed Germination
Corn husks can be used as a sterile medium for seed germination. The cellulose provides a moist, mold-free environment for seeds to sprout.
| Use | Method |
|---|---|
| Cooking | Wrap food in husks prior to steaming, baking, etc. |
| Crafts | Weave, tie, glue, or otherwise fashion husks into decorative items |
| Fire starter | Use dry husks as kindling |
| Fuel | Compress and burn husks directly or convert to syngas |
| Fiber additive | Process husks and incorporate into composite materials |
| Compost | Chop husks finely before adding to compost pile |
| Livestock feed | Add rough husks to livestock feed as fiber |
| Seed germination | Use husks as moist sterile medium for sprouting seeds |
This table summarizes some of the main uses of corn husks and how they are applied. The husks have a very wide range of applications thanks to their unique properties.

Health benefits of corn husks
While nutritionally lacking compared to the corn itself, corn husks do contain trace amounts of vitamins, minerals, antioxidants and plant compounds that can offer some health benefits:
Dietary fiber
The tough cellulose of corn husks provides insoluble fiber that can facilitate digestion. Though husks are rarely eaten directly, consuming them as part of medicines or teas adds small amounts of fiber.
Antioxidants
Corn husks contain various carotenoids and phenolic compounds that act as antioxidants in the body to counter free radicals and oxidative stress.
Anti-inflammatory effects
Compounds in corn husks appear to have an anti-inflammatory effect, which may help reduce inflammation for certain conditions. More research is still needed.
Diuretic properties
Infusions made from corn husks have shown some mild diuretic activity, potentially increasing urine output. This may help temporarily relieve swelling.
Antimicrobial activity
Extracts from corn husks have demonstrated antibacterial, antifungal, and antiviral properties in lab studies. This may help fight certain pathogens.
Anticancer potential
Early cell studies indicate that certain corn husk extracts may have cytotoxic effects against prostate, liver, breast and skin cancer cells. Much more research is needed.
Overall the limited health benefits of corn husks are not well proven and ingesting large amounts could have unwanted effects. But traditional medicinal uses suggest some potential value that may be explored further.
Are corn husks edible?
While corn husks are technically edible, they are not commonly consumed as food. Reasons for this include:
– **Tough texture** – The fibrous, stiff texture makes corn husks unenjoyable to eat.
– **Poor flavor** – Corn husks have a neutral starchy taste and fibrous consistency.
– **Low nutrition** – With only trace carbs, vitamins, and minerals, husks lack food value.
– **Digestive side effects** – Being high in cellulose, husks can cause gas, bloating, and obstruction issues if large amounts are eaten.
– **Pesticide contamination** – Most commercial corn crops are sprayed with pesticides that can persist on the husks.
– **Mold risk** – Fresh husks spoil quickly and may grow hazardous molds if not thoroughly dried.
– **Difficult to separate** – Removing the waxy, stringy husks from the corn cob and kernels is tedious.
While husks can technically be eaten after thorough cooking and drying, theexperience is highly unpleasant. The tiny traces of nutrients do not justify the poor taste and textural experience.
However, eating small amounts of husks may be tolerable when cooked into dishes like tamales. Corn husks can also be brewed into tea. But the husks are best used in applications that utilize their structural properties rather than nutritional value.
Are corn husks safe for animals?
Corn husks are generally safe when fed to livestock and pets in moderation. However, a few precautions are recommended:
– Choose fresh green husks whenever possible – dried yellow husks can be dusty and moldy.
– Wash and chop the husks to reduce choking hazard.
– Remove any corn kernels or cob pieces which could be a digestive irritant.
– Avoid husks treated with chemical pesticides or herbicides.
– Don’t make corn husks a primary component of the diet. The nutritive value is negligible.
– Limit husk consumption in young animals with developing digestive systems.
– Soak dried husks in water before feeding to rehydrate and soften the fiber.
– Monitor your animal’s stool – excessive corn husks can cause temporary constipation.
– Use corn husks sparingly in overweight/obese pets prone to gastrointestinal issues.
Overall, corn husks are not toxic to animals and can provide a modest amount of digestible fiber. But they lack other nutrients and therefore should not become a major dietary component. Monitor your animal’s health and adjust corn husk intake accordingly.
