Tips to use corn starch

Ways To Use Corn Starch For Various Purposes At Home

If you have cornstarch at home you can use it in many ways. Corn starch which is a fine white powder derived from the endosperm of corn kernels, has a wide range of cooking and non-culinary uses due to its unique properties. Do you know – corn starch body powder is highly recommended for rashes?

Here are some of the benefits of cornstarch:

  1. Thickening agent: Cornstarch is a common thickening agent used in cooking and baking. When mixed with liquid and heated, it forms a smooth, clear, and lump-free consistency, making it ideal for thickening sauces, soups, gravies, and pie fillings.
  2. Gluten free: As cornstarch is naturally gluten-free it is a suitable alternative for those with celiac disease or gluten sensitivity in recipes that traditionally call for wheat-based thickeners like flour.
  3. Texture enhancement: In baking, cornstarch can be used to create lighter and more delicate textures in cakes, cookies, and pastries. It helps tenderize and produce a finer crumb structure.
  4. Binding agent: Cornstarch can be used as a binding agent in recipes in fritters, cutlets or add to curry to help hold ingredients together.
  5. Gravy and sauce clarity: When added to gravies, sauces, and clear soups, cornstarch can improve clarity and give them a glossy appearance.
  6. Dessert fillings: Cornstarch is commonly used to make custards, puddings, and fruit pie fillings, as it thickens without imparting a noticeable flavor.
  7. Frying coating: It is often used as part of a batter or coating for frying foods. Cornstarch can create a crispy, golden exterior when frying.
  8. As body powder: Cornstarch is used as a natural and soothing body powder to help absorb moisture and reduce friction, making it useful for preventing chafing and diaper rash.
  9. First aid: Cornstarch can be used to help soothe minor skin irritations, such as sunburn, insect bites, and rashes. It can provide relief by absorbing excess moisture and reducing friction.
  10. Homemade playdough: Cornstarch is an essential ingredient in many homemade playdough recipes, creating a smooth and pliable texture.
  11. Cleaning agent: Cornstarch can be used as a natural cleaning agent for polishing furniture, cleaning windows, and even removing carpet stains.
  12. Shoe deodorizer: It can be used to absorb odors in shoes and as a natural alternative to commercial shoe deodorizers.
  13. Fire extinguisher: In some fire safety applications, cornstarch can be used as a non-toxic fire extinguisher for small kitchen fires involving grease or oil.

Store cornstarch in a cool, dry place and keep it tightly sealed to prevent moisture absorption, which can cause clumping. While cornstarch offers numerous benefits, it should be used in moderation in cooking and should not be considered a dietary staple due to its low nutritional value and high carbohydrate content.

Eyelid health

Protect Eyelids Health To Protect Your Eye Health

The eyelid plays an essential role in protecting your eyes and maintaining eye health. Eyelids are fold of skin that closes over both eyes to protect them from any type of injuries. There are upper and lower eyelids. Eyelid health can range from mild irritations to more serious conditions that require medical attention.

Functions of the eyelid:

  1. Protective barrier: Shields the eyes from dust, debris, and injury.
  2. Moisture maintenance: Spreads tears evenly across the eye to prevent dryness.
  3. Light regulation: Helps block excess light, aiding in vision and sleep.

Signs that may require medical attention:

  1. Swelling or redness: If your eyelid is persistently swollen, red, or painful, it could indicate an infection (e.g., cellulitis or a stye) or an allergic reaction.
  2. Drooping eyelid (Ptosis): If one or both eyelids suddenly droop, it may signal a nerve or muscle issue, potentially linked to conditions like myasthenia gravis or a stroke.
  3. Persistent lump: A small lump (e.g., a chalazion) that does not go away or grows larger may need medical evaluation.
  4. Painful bumps or blisters: Painful lesions or blisters could indicate shingles (herpes zoster) or other viral infections.
  5. Vision changes: Blurry vision, double vision, or vision loss alongside eyelid issues can suggest a more serious underlying problem (e.g., orbital cellulitis or thyroid eye disease).
  6. Discharge or crusting: Yellow, green, or excessive discharge, especially with swelling or redness, could indicate conjunctivitis (pink eye) or another infection.
  7. Bleeding or trauma: If your eyelid was injured or is bleeding without an obvious cause, this warrants medical evaluation.
  8. Persistent twitching (Myokymia): Occasional twitching is normal, but constant twitching might suggest nerve irritation or fatigue.
  9. Skin changes: New growths, dark patches, or irregularities on the eyelid skin might be a sign of skin cancer or another dermatological issue.

Common minor conditions:

  1. Dry eyes or blepharitis: Often linked to flaky skin, irritation, or clogged oil glands. These can usually be managed with warm compresses and proper hygiene.
  2. Styes: Small, red, and painful lumps often resolve on their own or with warm compresses.

Self-care tips for eyelid health:

  1. Maintain eyelid hygiene: Use warm compresses to clean and unblock oil glands. Gently clean with diluted baby shampoo or a lid scrub.
  2. Avoid rubbing eyes: Prevents irritation and reduces the risk of infection.
  3. Remove makeup: Always remove eye makeup thoroughly before sleeping.
  4. Monitor for irritants: Avoid allergens or harsh chemicals near your eyes.

    When to see a doctor?
  • If symptoms persist beyond a few days despite home care.
  • If pain, redness, or swelling worsens.
  • If you experience any of the vision-related symptoms above.
