[What is Andrographis?]

Andrographis paniculata is a bitter tasting annual plant, referred to as the “King of Bitters.” It has white-purple flowers and it is native to Asia and India where it has been valued for centuries for its numerous medicinal benefits. Over the past decade, andrographis has become popular in America where it is often used alone and in combination with other herbs for a variety of health purposes.

[How does it work?]

According to Memorial Sloan-Kettering Cancer Center, the active ingredient in andrographis is andrographolides. Due to the andrographolides, andrographis has potent anti-inflammatory and antimalarial properties. It also has antimicrobial properties, meaning it can help to fight off and prevent infections from harmful microorganisms such as viruses, bacteria and fungi. In addition, andrographis is a powerful antioxidant and it can help to prevent free radical induced damage to your cells and DNA

[Function]

Cold and Flu

Scientists have discovered that andrographis helps to boost the immune system by stimulating the body’s production of antibodies and macrophages, which are large white blood cells that scavenge harmful microorganisms. It is taken for both the prevention and treatment of the common cold, and it is often referred to as Indian echinacea. It might help lessen the severity of cold symptoms such as sleeplessness, fever, nasal drainage and sore throat.

Cancer, Viral Infections and Heart Health

Andrographis may also help to prevent and treat cancer, and preliminary studies done in test tubes found that extracts of andrographis help to treat stomach, skin, prostate and breast cancer. Due to the herb’s antiviral properties, andrographis is used to treat herpes and it is also currently being studied as a treatment for Aids and HIV as well. Andrographis also promotes heart health and can help to prevent the formation of blood clots as well as to dissolve already formed blood clots. In addition, the herb relaxes smooth muscles in the walls of blood vessels and thereby helps to reduce high blood pressure.

Additional Benefits

Andrographis is used to promote gallbladder and digestive health. It also helps to support and strengthen the liver and it is used in combination with other herbs in several Ayurvedic formulations to treat liver disorders. Finally, andrographis extracts taken orally have been found to help neutralize the poisonous effects of snake venom.

Dosage and Precautions

The therapeutic dose of andrographis is 400 mg, twice daily, for up to 10 days. Although andrographis is considered safe in humans, the NYU Langone Medical Center warns that animal studies suggest that it may impair fertility. Andrographis may cause unwanted side effects such as headaches, fatigue, allergic reactions, nausea, diarrhea, altered taste and pain in the lymph nodes. It may also interact with certain medications and as with any supplement you should consult your health care practitioner before taking the herb.

Iodine and Starch Experiment | Iodine Experiment | Starch Experiment | Science experiments for kids

Simple and easy experiment to demonstrate the iodine with starch reaction!

For this test you will need:
• Two test tubes
• Soluble starch powder
• Iodine solution
• Water
• Dropper
Procedure:
• Put some starch powder into a test tube and fill the test tube with water.
• Mix the starch in the test tube well until the starch dissolves in the water.
• Fill the other test tube with normal water.
• Place both the test tubes in a test tube stand.
• Using a dropper take iodine solution.
• Put some drops in each test tube.
• Observe that the test tube with starch solution turns to purple black color.
• The other test tube with normal water retains the color of iodine i.e orange or yellow.
Explanation:
Starch is a mixture of amylose and amylopectin, which are different forms of glucose/starch.
Amylose in starch is responsible for the formation of a deep blue black color.
Amylase is long polymer chains of glucose units connected by an alpha acetal linkage and looks much like a coiled spring.
However iodine is a potassium iodide reagent and it is not very soluble in water.
So, iodine is prepared by dissolving it in water in an aqueous solution of potassium iodide. This results in a linear tri-iodide ion (I3−) complex in iodine which is soluble.
This tri-iodide ion (I3−) slips into the coil of the starch causing an intense or deep blue-black color.

Details:

Tissue in the human body:

Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces.

A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

Two types of epithelial tissues: (1) Covering & lining epithelia and (2) Glandular Epithelium.

The number of cell layers & the shape of the cells in the top layer can classify epithelium.

Simple Epithelium – one cell layer
Stratified epithelium – two or more cell layers
Pseudostratified Columnar Epithelium – When cells of an epithelial tissue are all anchored to the basement Membrane but not all cells reach the apical surface.
Glandular Epithelium — (1) Endocrine: Release hormones directly into the blood stream and (2) Exocrine – Secrete into ducts.

Connective: contains many different cell types including: fibroblasts, macrophages, mast cells, and adipocytes. Connective Tissue Matrix is made of two materials: ground substance – proteins and polysaccharides, fiber — reticular, collagen and elastic.

Classification of Connective Tissue:
Loose Connective – fibers & many cell types in gelatinous matrix, found in skin, & surrounding blood vessels, nerves, and organs.
Dense Connective – Bundles of parallel collagen fibers& fibroblasts, found in tendons& ligaments.
Cartilage – Cartilage is made of collagen & elastin fibers embedded in a matrix glycoprotein & cells called chondrocytes, which was found in small spaces.
Cartilage has three subtypes:
Hyaline cartilage — Weakest, most abundant type, Found at end of long bones, & structures like the ear and nose,
Elastic cartilage- maintains shape, branching elastic fibers distinguish it from hyaline and
Fibrous Cartilage – Strongest type, has dense collagen & little matrix, found in pelvis, skull & vertebral discs.

Muscle: is divided into 3 categories, skeletal, cardiac and smooth.
Skeletal Muscle — voluntary, striated, striations perpendicular to the muscle fibers and it is mainly found attached to bones.
Cardiac Muscle — involuntary, striated, branched and has intercalated discs
Smooth Muscle — involuntary, nonstriated, spindle shaped and is found in blood vessels & the GI tract.

Nervous: Consists of only two cell types in the central nervous system (CNS) & peripheral nervous system (PNS):
Neurons – Cells that convert stimuli into electrical impulses to the brain, and Neuroglia — supportive cells.
Neurons — are made up of cell body, axon and dendrites. There are 3 types of neurons:
Motor Neuron — carry impulses from CNS to muscles and glands,
Interneuron – interpret input from sensory neurons and end responses to motor neurons
Sensory Neuron — receive information from environment and transmit to CNS.
Neuroglia — is made up of astrocytes, oligodendrocytes, ependymal cells and microglia in the CNS, and schwann cells and satellite cells in the PNS.
