We walked back to the kitchen, and Luis made tea from the guava leaves while I watched, the water darkening to a pale gold. It tasted bitter-green, a little earthy, nothing like the sweet teas from the store. I drank it slowly, and I thought about my father and his pillbox, and about the numbers on the clinic's screen, and about Ana's handwriting in the journal: for blood, for liver, for the heart.
"I want to ask a doctor," I said. "A real doctor, properly. Before anything."
Luis nodded, satisfied. "That," he said, "is exactly what Ana would have done."
Dr. Priya Patel has been at our clinic for fifteen years, and she has a way of telling the truth that makes people feel respected rather than scolded. I booked my father an appointment, and I went with him, carrying Ana's journal in my bag like a student carrying homework.
My father sat on the examination table, his pillbox in his jacket pocket, and told her about the garden and the four leaves. Dr. Patel listened the way she always listens, without interrupting, and then she opened the journal and looked at the pressed leaves.
"Your grandmother had good instincts," she said. "And she had something else, too — she knew the difference between support and cure. That difference matters more than anything else we will talk about today."
She turned to my father. "Jorge, I want to be plain with you. No leaf, no tea, no powder, cures diabetes. No leaf cures cancer. No leaf on its own fixes a fatty liver or makes high blood pressure go away. These are serious conditions. They need proper diagnosis, and they need treatment. Anyone who tells you otherwise is selling something."
My father nodded. He has heard plain talk before, and he prefers it.
"But," Dr. Patel went on, "there is a second truth, and it is also plain. These plants — moringa, guava leaf, green tea, papaya leaf — have been used for a very long time, in many parts of the world, and some of them have real research behind them. Green tea is one of the most studied plants there is. Moringa is rich in nutrients and antioxidants. Guava-leaf tea has tradition behind it in Asia and Latin America, and some studies suggest it may help with blood sugar after meals and with cholesterol. Papaya leaf has a long history of use for the liver and for inflammation. What they may do, at their best, is support the body — help it a little, alongside everything else."
She held up one finger. "Alongside. That is the word that matters. Alongside your medicine, not instead of it. Alongside food that is good for you, and walking, and sleep, and managing stress. The leaves do not replace any of that. They walk beside it."
I felt something in my chest loosen. That was the sentence I had been waiting for without knowing it.
"And there is a warning," she said, "and it is important. Some plants can interact with medicines. If a plant affects blood sugar or blood pressure, and you are already taking medicine for blood sugar or blood pressure, the two can add up in ways we do not want. So before you change anything, before you start a daily tea or a powder, you ask me. That is the rule. Always."
She looked at the journal again. "One to two cups of green tea a day is reasonable for most people. Guava-leaf tea after meals, in moderation. Moringa powder in a smoothie, a small amount. Papaya leaves in soup, now and then. These are gentle, traditional uses. They are not treatments. And if anything feels wrong — dizziness, stomach trouble, anything unusual — you stop and you call me."
I asked the question I had been avoiding, the one from the boldest headlines. "And the bigger claims? The ones that say leaves can fight cancer, or replace medicine altogether?"
Dr. Patel did not hesitate. "Those claims are not proven, Maria, and you know it as a nurse. Some laboratory work is interesting, and researchers are still studying it, but a laboratory dish is not a person, and a headline is not evidence. No one should ever stop prescribed treatment because of a plant, and no one should ever promise a cure from a teapot. What we have here is tradition, some good research, and a lot of good sense. That is plenty. We do not need to invent more."
My father reached across and squeezed my hand. "I never wanted a miracle," he said quietly. "I just wanted to feel like I was doing something, not only taking something."
Dr. Patel nodded. "That is exactly what this is, Jorge. Doing something — walking, cooking, drinking your tea — alongside the medicine that keeps you safe. Both matter. Neither replaces the other."
My father laughed, a little embarrassed. "So the garden can stay, but the pills stay too."
"Exactly," Dr. Patel said, and she smiled. "The pills stay. The garden stays. And you keep coming to see me, and we watch the numbers together."
On the way home, my father was quiet in the car, and then he said, "Your grandmother would have liked that doctor."
I thought about Ana, and her journal, and her rule of both — the garden and the doctor, never one instead of the other. It turned out Luis had been right. It turned out Ana had been right. And it turned out that the most honest thing anyone had said about the four leaves all week was the simplest one: they may help, they do not cure, and the doctor comes first.
