What is this herbal treatment (Phytotherapy)?
Simply put, Phytotherapy is the use of plants, herbs, or substances derived from them to manage disease. These are also called phytomedicines or herbal medicines.
The important thing is that this is considered complementary medicine . That is, it is a treatment that you can receive in addition to the Western treatments that you would normally receive from a doctor. But it should never be used as a substitute for the main treatment.
Imagine, you are taking the medicine prescribed by your doctor for diabetes. In the meantime, you feel like using a certain herbal product. That's where this becomes a complementary therapy. But before doing so, you should definitely talk to your doctor.
In countries like America and Sri Lanka, these are sold as dietary supplements. This means that there has been no major scientific research into their efficacy , safety, or quality. However, in some European countries, these are strictly regulated and can only be purchased with a prescription from a doctor. Sri Lanka also has varying levels of regulation.
How do these affect the body?
Herbal remedies can affect our body's processes in many different ways. Researchers are still investigating this. Some have been found to affect brain chemicals, the immune system, and appetite.
Another way is to prevent damage to the cells in our body. Think of the cells in our body as little bricks. These bricks are damaged by certain diseases, such as cancer and dementia . Researchers believe that certain chemicals in these plants, called phytochemicals , can act as a shield that prevents this damage.
Some examples currently under research
Below are some herbal remedies that researchers are focusing on. But keep in mind that many of these are still in the research stage .
- Ginger: May help relieve symptoms of nausea and vomiting. However, research is still ongoing on how safe ginger is for morning sickness during pregnancy.
