The fruits are dark-brown cylindrical pods, 2' long, which also hold the flattish, brown seeds (up to 100 in one pod). A postal stamp was issued by the Indian Postal Department to commemorate this tree.

Pharmacological profile of Aragvadha
There are many Cassia species worldwide, which is used in herbal medicine systems. This particular family of plants is used widely for their laxative actions. Cassia fistula Linn. is no exception. It is often used as a highly effective moderate laxative that is safe even for children. However, in large doses, the leaves and bark can cause vomiting, nausea, abdominal pain and cramps. Cassia fistula Linn. is also employed as a remedy for tumors of the abdomen, glands, liver, stomach, and throat, for burns, cancer, constipation, convulsions, delirium, diarrhea, dysuria, epilepsy, gravel, hematuria, pimples, and glandular tumors. The seeds are attributed with antibilious, carminative, and laxative properties while the root is used for adenopathy, burning sensations, leprosy, skin diseases, syphilis, and tubercular glands. The leaves are used in erysipelas, malaria, rheumatism, and ulcers. In Brazilian herbal medicine, the seeds are used as a laxative and the leaves and/or bark is used for pain and inflammation. Various laboratory studies report that aragwadha has evidenced antioxidant, hypoglycemic, Acetylcholinesterase (AChE) inhibitor, antibacterial, antifungal, anticandidal activity, antiviral, laxative, liver protective, mild estrogenic, antitumorous, cholesterol lowering, pain relieving, and fever reducing actions.
Pulp of pod contains anthraquinone glycosides, sennosides A & B rhein and its glucoside, barbloin, aloin, formic acid, butyric acid, their ethylesters and oxalic acid. Presence of pectin and tannin are also reported. Seed gave galactomannan free sugard and free aminoacids, extract laxative, carminative, cooling and antipyretic. Flowers give free rein to its glycosides Sennosides A & B.
The synonyms play an important role in correct identification of the plant. Apart from the above mentioned synonymns, nighantus (lexicons) suggests names like suvarnaka (beautiful tree), dirghaphala (one which has long fruits), naradipa, apaghataka, swarnahu are the few names of the plant. In Rajanighantu under prabhadradi varga mentions few more synonymns such as nripadhruma, rajataru, aruna, karnabharanaka and maharajadhruma.
Karnikara has been considered as synonym by Charaka but in Dhanwantari Nighantu it is considered as separate drug.
Properties and formulations
Aragwadha is mridu (soft) in guna (heavy), bitter and sweet in taste and madhura (sweet) in vipaka due to which it is very safe to be used in bala (children), vriddha (aged), sukumara (delicate constitution) and urakshata (injuries to chest) as well as in kshina (debilitated) too. 
Charaka has mentioned its uses in following conditions:
- Jwara - Aragwadha given with grape juice[Cha. Sa. Chikitsa Sthana 3/232]
- Kushta (skin Ailments) – Decoction for bath and internal intake [Cha. Sa. Chikitsa Sthana 7/97]
- Visarpa(Herpes) – Leaf decoction or anointment with paste of leaves[Cha. Sa. Chikitsa Sthana 21/88]
- Kamala(Jaundice) – Phalamajja (fruit pulp) is taken with sugarcane juice 
- Urusthambha- Leaves are boiled and eaten without adding salt is useful in urusthambha[ Cha. Sa. Chikitsa Sthana 27/25]
- Pittodara – Phalamajja decoction. [ Cha. Sa. Chikitsa Sthana 18/69-70]
- Twakroga – Leaves processed with buttermilk is applied as paste [ Cha. Sa. Sutra Sthana 3/17]
- Haridrameha – Phalamajja is given in kashaya form.
For vrinaprakshalana aragwadha patra and jati patra kwatha (leaves of Jasmine plant) are used for washing wound.
Aragwadha with bile of cow and katutaila(mustard oil) is used in skin ailments.
Apart from this aragwadha is used in many more ways which will be discussed in the context of different formulations.[4-5]
Aragwadha leaves, root, bark and flowers are used for medicinal purpose. More specifically, fruit pulp is used for purgation where as flowers are used for urinary strangury. Fruit pulp is sweet in taste, if not processed it gets worm infested. Thus fruit pulp should be used only after proper processing.
Charaka mentions aragwadha in the context of vamana and asthapana[Cha.Sa. Sutra Sthana 1/82]. Apart from this it also finds mention in Charaka Sutra Sthana 4th Chapter under kushtaghna, vamanopaga and kandughna dashemani. In Charaka Vimana Sthana aragwadha has been considered under tiktaskandha [ Cha. Sa.Vimana Sthana 8/164]. Sushruta mentions usage of aragwadha in ksharakalpa. Aragwadha has been mentioned in aragwadhadi gana and shyamadi gana . Even though Charaka mentions khadira as best drug in kushta [Cha. Sa. Sutra Sthana 25] It may be seen that in Charaka Sutra Sthana 2nd chapter aragwadha has been preferred over khadira. For external usage it may be considered that aragwadha is best, whereas for internal usage khadira is choice of drug in kushta. [6-7]
Below age four years the drug is not advised, because of possible complications and in children above 12 years, drug may not give the desired benefit. As both aragwadha and draksha(grapes) are mild purgative in nature may not induce the desired purgation if given to children above 12 years. Chakradutta mentions the usage of aragwadha with drasksha in pittajajwara. Aragwadha is purgative but when administered alone may bring about untoward side effects like colicky pain so is usually administered with any suitable adjuvants. [8-9½]
Aragwadha phala majja is preferably used in sheetakashaya (or phanta form as tannin content present in it, when boiled tannin in it will increase and its purgative action will be reduced. Apart from this aragwadha with suramanda, sauviraka and kolasidhu can be given to those who are addicted to alcohol. Where as those who prefer amla rasa (sour taste) can be administered with dadhimanda. In general, for others it can be given with amalaki swarasa which will potentiate the action of aragwadha and will also reduce its untoward effects like colicky pain. In eczema and skin ailments like urticarial rashes aragwadha leaves are made into paste with kanji and applied.(Vangasena) [9½-10]
In the formulation mentions in verse 11, 16 tola or 32 tola aragwadha phala majja is dissolved in water and sheeta kashaya (cold infusion) is prepared out of this. But at this dosage it may not be tolerated at present context. Therefore it is said that for sheeta kashaya, aragwadha phala majja is taken in 1 tola pramana where as to dissolve in trivrita or bilva kashaya it may be taken in 6 masha. This form of administration may be for those who desire to take the drug in a simple form as it is easy to administer. Rock salt and honey are added to improve the taste and efficacy of the yoga. Trivrita added to aragwadha will facilitate and hasten the action of aragwadha.
Aragwadha even though has tannin in it, when dissolved with trivrita kwatha and jaggery retains its purgative effect. Avaleha (linctus) form of the drug can be preserved for longer duration. Thus the drug prepared in this form can be used as and when required.
The avaleha should be given to the patient according to his koshtha for inducing virechana. 
Milk is mixed with aragwadha fruit pulp, it is boiled and cooled. Cream is extracted from it, by which ghee is prepared. This can be used for purgation. Other than above said method, ghee (unprocessed) can also be processed with aragwadha fruit pulp and amalaki fruit juice which may also be used to induce purgation. Ghrita prepared from the decoction of the root of aragwadha is very much useful in kushtha. Ghrita like avaleha can be preserved for longer duration and can be used accordingly. Apart from this ghrita can be used as remedy in pitta dosha dominance as well vata dosha dominance where decoction may not be that much suitable.
Three ghrita preparations are told here to suit the need and constitution of the individual. One with simple aragwadha phala majja, other preparation to which amalaki juice is added and third being added with dashamoola and other virechaka dravyas. Thus prepared ghee can be used to induce purgation. 
Arishta (medicated wine) can be preserved for longer duration. It is easy to administer too. Those who can tolerate aragwadha in arishta form can be administered with the above said preparation. Preparation of aragwadha in arishta (medicated wine) form can be given to patients to induce purgation. 
Root of aragwadha is good antipyretic as well as good purgative. Leaves of this plant is good saaraka (that increase intestinal movements). Aragwadha fruit pulp with tamarind fruit pulp taken in the night helps to relieve constipation. Aragwadha fruit pulp can be given even with food and article which patient desires. Foods and articles should be either sweet, pungent or salty in taste. Astringent and bitter even though patient desires should not be used as it hinders drug absorption.
