1) Haematinics :-

Haematinics refer to nutrients that are necessary for the production of healthy red blood cells. These include iron, vitamin B12, folic acid, and vitamin C.

Iron is a crucial component of haemoglobin, the protein in red blood cells that carries oxygen throughout the body. Iron deficiency can lead to anaemia, a condition characterized by low levels of red blood cells and decreased oxygen delivery to tissues. Foods rich in iron include red meat, poultry, fish, beans, lentils, tofu, fortified cereals, and spinach.

Vitamin B12 is essential for the formation of red blood cells and the maintenance of the nervous system. It is found in animal products such as meat, fish, eggs, and dairy, as well as fortified cereals and nutritional yeast. Vegetarians and vegans are at risk of vitamin B12 deficiency and may need to supplement their diets.

Folic acid, also known as folate, is important for the production and maintenance of new cells, including red blood cells. It is found in leafy green vegetables, fruits, beans, and fortified cereals. Women who are pregnant or planning to become pregnant are advised to take a folic acid supplement to prevent neural tube defects in their babies.

Vitamin C is needed for the absorption of iron from plant-based foods and for the production of collagen, a protein that helps form the structure of red blood cells. Foods rich in vitamin C include citrus fruits, berries, kiwi, broccoli, peppers, and tomatoes.

2) Expectorants :-

Expectorants are a type of medication that help to loosen and thin mucus in the respiratory tract, making it easier to cough up and clear from the lungs. They are commonly used to treat respiratory conditions such as bronchitis, pneumonia, and asthma, as well as coughs that produce thick or sticky mucus.

Expectorants work by increasing the volume and decreasing the viscosity of mucus, which helps to make it easier to cough up. They do this by stimulating the production of more fluid in the respiratory tract, which helps to break up the thick, sticky mucus and make it easier to move. Some expectorants also have a mild numbing effect on the respiratory tract, which can help to reduce coughing and irritation.

There are several different types of expectorants available, including natural remedies such as honey and eucalyptus oil, as well as over-the-counter medications such as guaifenesin and bromhexine. Guaifenesin is one of the most commonly used expectorants, and is available in a variety of different formulations, including tablets, capsules, and syrups. It is generally considered safe and effective, although it can cause side effects such as dizziness, drowsiness, and nausea in some people.
