Sea Moss Overview
Sea moss, also known as Irish moss, is a type of seaweed native to the Atlantic coast of Europe and North America. It is a rich source of nutrients, including iodine, calcium, and potassium. It is also a good source of carrageenan.
Sea moss has been traditionally used as a natural remedy for a variety of conditions, such as respiratory problems (e.g, cough), digestive issues, and thyroid disorders. It is also claimed to have anti-inflammatory properties and to be beneficial for the skin and hair.
As a dietary supplement, it is most commonly marketed as a plant-based source of antioxidants.
Abemaciclib Overview
-
Abemaciclib is used in combination with an aromatase inhibitor such as anastrozole (Arimidex), exemestane (Aromasin), or letrozole (Femara) to treat a certain type of hormone receptor-positive, early breast cancer. Abemaciclib is also used along with fulvestrant (Faslodex) to treat a certain type of hormone receptor-positive, advanced breast cancer (breast cancer that depends on hormones such as estrogen to grow) or breast cancer that has spread to other parts of the body after treatment with an antiestrogen medication such as tamoxifen. Abemaciclib is also used along with anastrozole (Arimidex), exemestane (Aromasin), or letrozole (Femara) as a first treatment of hormone receptor-positive, advanced breast cancer or breast cancer that has spread to other parts of the body. Abemaciclib is also used alone to treat a certain type of hormone receptor-positive, advanced breast cancer or breast cancer that has spread to other parts of the body in people who have already been treated with an antiestrogen medication and chemotherapy. Abemaciclib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
