Oil bath, almost a forgotten weekly routine followed by every South Indian family until 3 or 4 decades ago, offers pretty much the same benefits of Ayurvedic massage. Nowadays people prefer to visit Ayurvedic clinic for massaging therapy, and spend a few hours & a few bucks there, but they take oil bath at home only on the day of Deepavali festival every year as a religious ritual.
Cottonseed milk is the traditional vegan milk used by the people in the villages near Madurai, my home town, for making nutritious desserts. As a part of my college education, I served as an NSS (National Service Scheme) volunteer. We used to camp in the surrounding villages during summer vacation to understand the living conditions of the people and also help them improve their standard of living. We were always greeted with a glass of delicious cottonseed milk dessert in almost every household in those villages. Normally they used to grind large quantity of cottonseeds everyday and used as a fodder feed particularly to milking cows. Apparently cottonseed milk is beneficial to lactating mothers as well. Besides it is useful to everyone during summer to keep the body cool.
Chukku-malli kaapi is a traditional South Indian digestive elixir prepared using dried ginger & other spices, herbs and palm jaggery. Since Indian medicine systems like Siddha or Ayurveda recommends to take fresh ginger in an empty stomach in the morning & dried ginger later in the day to improve the digestion.
Porivilangai is a traditional sweet made of pan-roasted rice & palm jaggery. Our grandmother usually prepared these laddus for Deepavali and my aunts used to keep them for us till our visit during summer. In those days these flavorful porivilangai were made into hard-to-bite orange sized balls but now I have made small soft laddus that can be stored only for few days.
Kummiyanam is a nutritious dessert made of rice, assorted legumes & palm jaggery prepared by the people in Tirunelveli, Nagerkoil, or Kanyakumari. It is offered to the lamented souls while remembering them in Aadi month (a Tamil calendar month usually falls between 15th of July & 15th of August). In this month we remember departed men on Aadi amavasyai (no moon day) and women on aadi irudhi (last day of Aadi). Likewise, I heard Japanese visiting cemeteries during the same period to remember the departed.
