Amaltas is known by various names across different regions and languages:
Uses of amaltas are endless, especially due to their various Ayurvedic pharmacological properties:
Due to these properties, this medicinal herb is effective in treating rheumatoid arthritis, gout, pruritus, skin diseases, jaundice, dysuria, blood disorders and cardiovascular diseases.
This medicinal herb (Cassia fistula) has numerous health benefits because of the numerous pharmacological effects associated with it. Here's a detailed look at how it can benefit various health conditions:
Amaltas has mild laxative properties due to anthraquinone glycosides found in its fruit pulp. These compounds help stimulate bowel movement and soften stools, providing relief from constipation. The fruit pulp, when taken in moderate amounts, is very effective in the treatment of chronic constipation without resulting in dependence or severe side effects as those from synthetic products. Typically, 1–2 teaspoons of the pulp are recommended.
Due to the anti-inflammatory and mild laxative action of Amaltas, this herb is helpful in treating piles. Making the stools soft and reducing the pressure during the bowel movement assists in reducing the pressure on haemorrhoids. Further, it is also effective in the reduction of inflammation that is commonly felt in piles. Haemorrhoids may be relieved by applying externally a paste made from the leaves of this medicinal herb.
Amaltas has been used in traditional medicine to treat complaints related to hyperacidity. Its cooling effect aids in alleviating the impact of excessive stomach acid, relieving the sufferer from heartburn and indigestion. This medicinal herb's bark or its leaves can be prepared into a decoction to effectively ease digestion and reduce stomach acidity.
This medicinal herb is beneficial for treating rheumatoid arthritis because it has anti-inflammatory properties. Substances in the plant have anti-inflammatory properties that may also assist in controlling swelling of the joints familiar with this disease. Drinking a decoction of this tree's bark or leaves effectively manages arthritis.
This plant has been used conventionally to manage different skin disorders, such as allergies. These properties will prove particularly useful in skin conditions such as dermatitis, eczema, and other allergic skin reactions, where there is inflammation, microbial infection, itching, redness, and swelling. Amalta paste can also be used for external applications to treat the inflamed affected areas.
Due to its antispasmodic effects, it can be used to treat abdominal pain and cramps. It may be especially effective for intestinal colic or menstrual pain. The decoction of its bark or leaves is warm and can be ingested to lessen abdominal pain.
It also has antibacterial and anti-healing properties. It is also used externally for minor injuries, cuts or bruises by preparing a paste from the leaves or boiling the bark. It can help avoid the contraction of diseases, which might slow down the healing process due to the formation of scar tissues.
Because of the expectorant nature of Amaltas, it is effective in controlling coughs, especially the dry ones. A decoction of its bark or a tea prepared from its flowers should be taken in case of throat irritation and to facilitate the expulsion of phlegm.
There are some reports that the plant may possess a cardioprotective effect. It may also contain antioxidants that can help reduce the amount of oxidative stress in the heart and enhance the general health of the heart. But, further research is required to confirm these cardioprotective effects.
It also has diuretic effects and may be used in all sorts of urinary issues. It may also help increase the rate of urine production which may be of value in clearing toxins and preventing UTIs. A decoction of the root or bark of Amaltas traditionally serves this purpose.
It has many benefits to a person's health but should be used carefully and under the direction of a healthcare provider. That is why, if taken inappropriately or in large quantities, it is possible to experience side effects. It is always advisable to take the drugs in small amounts and then see how your body is going to react. If you are on medication or have certain known diseases, consult your doctor before taking it as part of your treatment.
This medicinal herb (Cassia fistula) is a multipurpose tree with different plant parts employed in folk medicine. Here's how to use other parts of Amaltas:
It is always advisable to start with small quantities and work your way up if needed. For external use, do a skin test to know if you have an allergy to the product. It should be used under the recommendation of a qualified Ayurvedic practitioner or healthcare provider if one has a pre-existing medical condition or is on medication.
Bear in mind that this medicinal herb is powerful, and therefore, its application should be reasonable. In particular, consuming large amounts of the amaltas fruit pulp may cause stomach upset or diarrhoea. Pregnant and breastfeeding women and people should not take this medicinal herb with chronic diseases without consulting their doctor. Ensure each preparation is correctly identified to avoid using incorrect or toxic plant species.
While Amaltas is generally considered safe when used appropriately, potential side effects may include:
These side effects are usually mild and only manifest in rare cases when the drugs are used as prescribed.
Amaltas offers a wide range of health benefits, from easing constipation and piles to aiding skin disorders, joint pain, and urinary issues. With anti-inflammatory, laxative, antispasmodic, and antibacterial properties, it serves as a natural remedy in many traditional treatments. However, despite its therapeutic potential, it must be used with care. Overconsumption or misuse can lead to side effects like diarrhoea, allergic reactions, or interactions with medications. Therefore, it is essential to follow proper dosages and consult a doctor, especially for pregnant women, the elderly, or individuals with pre-existing conditions, to ensure safe and effective use.
