The Story

The Boy Who Was Always Sick

In a Tiwa village perched on a misty hill in central Assam, there lived a boy named Hambir who caught every illness the seasons could throw at him. Monsoon fevers. Winter coughs. Spring allergies that made his eyes water like tiny rivers. The other children ran and climbed and swam; Hambir sat on the veranda with a blanket around his shoulders, sneezing.

“Take him to Oja Mahir,” the neighbours told his mother. “The old healer knows things the hospital doesn’t.”

Oja Mahir lived at the edge of the village, in a bamboo house surrounded by a garden that looked more like a forest. Plants grew everywhere — on the ground, up the walls, hanging from the roof, spilling out of pots made from hollowed logs. The air smelled of ginger and basil and something sharp that made Hambir’s nose tingle.

The First Lesson

“So you’re the boy who is always sick,” said Oja Mahir, peering at Hambir through eyebrows thick as caterpillars. He was very old — so old that nobody knew his exact age — but his hands were steady and his eyes were bright.

“Can you cure me?” asked Hambir.

“I can do better,” said the old healer. “I can teach you to cure yourself. But it will take time. You will have to come here every morning and learn.”

Hambir’s mother agreed. And so, every morning at dawn, Hambir walked to the healer’s garden and began his education in the pharmacy of the forest.

The first lesson was simple. Oja Mahir pointed to a plant with broad, fuzzy leaves. “This is manimuni,” he said. “People of Assam have used it for centuries. Eat two leaves every morning and your memory will sharpen. It also heals wounds.”

“How does a plant heal a wound?” asked Hambir.

“How does your body grow taller?” the healer replied. “Some things work without needing to explain themselves.”

The Forest Pharmacy

Over the following weeks, Hambir learned the names and uses of dozens of plants. Neem leaves for skin infections. Tulsi tea for colds. Turmeric paste for inflammation. Bael fruit for stomach troubles. Black pepper and honey for stubborn coughs that refused to leave.

But Oja Mahir taught more than recipes. He taught Hambir to observe. “Watch the animals,” he said. “When a wild elephant has a stomach ache, she eats clay from the riverbank. When a monkey has a fever, he chews neem bark. The animals were the first doctors. We Tiwa people learned from them.”

Hambir began keeping a notebook. He drew each plant carefully, writing its Tiwa name, its uses, and where to find it. The notebook grew thick. His sneezes grew fewer.

The Test

One rainy afternoon, a child from the neighbouring village arrived at Oja Mahir’s door, crying. Her little brother had stepped on a thorn and the wound had turned angry and red.

Oja Mahir looked at Hambir. “What would you do?”

Hambir’s heart raced, but his hands were steady — the healer’s hands. He cleaned the wound with boiled water and turmeric. He crushed fresh manimuni leaves into a paste and applied it as a poultice. He wrapped the foot in a clean banana leaf and told the girl to change the dressing every morning.

Three days later, the wound was healing cleanly. The girl’s family brought Oja Mahir a basket of oranges in thanks. The old healer passed the basket to Hambir.

“You earned these,” he said.

The Apprentice Becomes the Keeper

Hambir wasn’t always sick anymore. The daily walks, the fresh herbs, the knowledge of what his body needed — all of it had made him strong. But more than that, he had found his purpose.

When Oja Mahir was too old to tend his garden, Hambir took over. He expanded it, planting new species he found on forest walks, labelling each one in Tiwa and English. He became the village’s young healer — not a replacement for modern medicine, but a keeper of the old knowledge that the forests had been offering for free all along.

“Plants are the original pharmacy,” Hambir would tell the children who visited his garden. “They were here before pills, before hospitals, before doctors with degrees. They don’t charge money. They just grow, and heal, and ask nothing in return.”

The end.

Here is a taste of what Level 1 looks like for this lesson:

Level 1: Explorer — Python
import numpy as np
import matplotlib.pyplot as plt

# Your first data analysis with Python
data = [45, 52, 38, 67, 41, 55, 48]  # measurements
mean = np.mean(data)

plt.bar(range(len(data)), data)
plt.axhline(mean, color='red', linestyle='--', label=f'Mean: {mean:.1f}')
plt.xlabel("Sample")
plt.ylabel("Value")
plt.title("Medicinal Plants — Sample Data")
plt.legend()
plt.show()

This is just the first of 6 coding exercises in Level 1. By Level 4, you will build: Research Plants That Became Medicines.
